How long can I store minced garlic?

I will mince 2 bulbs at a time. I make sure each clove has no blemishes and clip off the core on each clove. I place all the cloves in a small food processor, add a pinch of salt and a drizzle of olive oil, then process. I keep it in a glass jar in the fridge. I use it up in 3-4 days but as it ages it discolors and it's potency decreases.

The minced in oil or water you buy in jars is mostly dehydrated and has a preservitive added. Each brand differs. I have tried in oil 1 week tops, and water and salt about 4 days.

Then I tried putting in water and freezing  it works . I put about 1 T in plastic wrap add some water make sure all is moist then I freeze. I took it out 2 weeks later left infridge a while then used results were good.

I also freeze my Fresh Basil  dry in layers. lose some flavor but better then dry.

ChaosGirl;...I have severe arthritis and my hands are pretty clawed up, so chopping has become more of a problem over the years.

Hello CG!

Maybe this preparation is something for you. It's called garlic confit and needs no chopping and... the garlic will stay usable for a few weeks!

Also, you will have an excellent byproduct which is garlic oil, to be used on salads, for frying potatoes etc. Also, you can eat many entire cloves without spreading that garlic odor! And above all, it's easy to do.

Get some garlic bulbs. The only thing you need to do is to give them a nice bang with a rolling pin or so to brake the bulbs into cloves. Get the cloves out, but do NOT peel them!

Make a mixture of half olive oil and half sunflower oil, or just olive oil or just sunflower, it doesn't matter too much.

Put the unpeeled cloves in the oil together with a sprig of thyme and/or some rosemary.

Put it on your stove, but reduce the fire as if you were hardly simmering anything. I mean, the mixture cannot get higher than 100°C, the boiling point of water. 80°C is more like it. Let the preparation sit on the fire for 60 minutes or longer, it doesn't matter.

Put the fire out, but leave the preparation to cool entirely.

When cooled, sieve, but preserve the delicious garlic oil. Take one clove at a time and squeeze a little. The clove will simply pop out of the peel. You can preserve the cloves in the garlic oil you just made. I save the cloves in a small plastic container and put it in my fridge.

You'll love this!

Just to remind you, garlic is a vector for botulism. When you start storing it oil, even after cooking, you set up conditions for toxicity. Keep it refrigerated and use it within a few days. Same for the oil itself.

Phatch!   Right you are 

. The Florida local  county health depts. sent out a notices  about a year ago re. garlic cooked or raw  stored in oil, without the use of a known preservative like sodium ben. or ascorbic acid.

Garlic confit is a fabulous thing. That is a great way to save it for quite some time. 

If I need lots of chopped garlic, I pulse garlic in the food processor (already peeled - nothing but the garlic) until it reaches desired consistency.  I then cover it with good olive oil in a plastic container and use it as needed over the next week or two - but no more than that. Phatch is right, you gotta be careful with storing garlic too long...

Boutulism has long been the boogyman of the food science world, particularly when USDA and FDA are involved. As we've seen from past discussions on this topic, in general the actual risk levels do not justify the hysteria.

So it is with garlic-in-oil. There is, to be sure, a lot of anecdotal information, and repeating of the dire warnings. Almost always, however, they say "could cause," "may cause," "the possibility exists" and similar qualifiers. So let's exclude the bloggers, and sloppy food writers, and conventional wisdom and look at the facts.

Boutulism from garlic in oil did not emerge as a problem until the mid-1980s. In 1985 or 1986 (depends on which authority you choose), there was an outbreak in which 36 or 37 people (again, depends on authority cited) came down with boutulism after eating improperly stored garlic in oil at a British Columbia restaurant. This led to research into the situation. In 1988 the CDC issued a report on its research. According to the abstract:

"Diagnosis of botulism in two teenaged sisters in Montreal led to the identification of 36 previously unrecognized cases of type B botulism in persons who had eaten at a restaurant in Vancouver, British Columbia, during the preceding 6 weeks. A case-control study implicated a new vehicle for botulism, commercial chopped garlic in soybean oil (P less than 10(-4))."

According to a 1998 article in SafeFood News, this led to new regulations controlling commercial production:

"……This was followed by a 1988 laboratory investigation into the survival of and toxin production by C botulinum in garlic-in-oil preparations. In 1989, 3 people in Kingston, NY, became ill, also from a garlic-in-oil infusion. Thus, in 1989 the FDA issued a ruling, ordering the removal from store shelves of all commercial garlic-in-oil preparations that lacked an acidifying agent, followed by a mandate requiring the addition of an acidifying agent (such as phosphoric or citric acid) to all commercial garlic-in-oil preparations. Acid prevents the growth of the C botulinum, so any spores that might be present in an infusion will not be able to flourish and produce toxin. The acid must be added as the recipe is being prepared."

 In other words, the entire hoopla is based on only two events

But what about those who make their own garlic in oil? Research performed by the National Center for Home Food Preservation at the University of Georgia confirmed that mixtures of garlic in oil stored at room temperature are at risk for the development of botulism. Garlic in oil should be made fresh and stored in the refrigerator at 40 °F or lower for no more than 7 days. It may be frozen for long term storage for up to several months. Package in glass freezer jars or plastic freezer boxes, leaving ½-inch headspace. Label, date and freeze.

So, the long and the short of it is that you can safely prepare and use garlic in oil, so long as you take normal precautions.

http://cecalaveras.ucdavis.edu/garlic.htm BOTULISM WARNING Regardless of its flavor potency, garlic is a low-acid vegetable. The pH of a clove of garlic typically ranges from 5.3 to 6.3. As with all low-acid vegetables, garlic will support the growth and subsequent toxin production of the bacterium Clostridium botulinum when given the right conditions. These conditions include improper home canning and improper preparation and storage of fresh herb and garlic-in-oil mixtures. Moisture, room temperature, lack of oxygen, and low-acid conditions all favor the growth of Clostridium botulinum. When growing, this bacterium produces an extremely potent toxin that causes the illness botulism. If untreated, death can result within a few days of consuming the toxic food. STORING GARLIC IN OIL Extreme care must be taken when preparing flavored oils with garlic or when storing garlic in oil. Peeled garlic cloves may be submerged in oil and stored in the freezer for several months. Do not store garlic in oil at room temperature. Garlic-in-oil mixtures stored at room temperature provide perfect conditions for producing botulism toxin (low acidity, no free oxygen in the oil, and warm temperatures). The same hazard exists for roasted garlic stored in oil. By law, commercially prepared garlic in oil has been prepared using strict guidelines and must contain citric or phosphoric acid to increase the acidity. Unfortunately, there is no easy or reliable method to acidify garlic in the home. Acidifying garlic in vinegar is a lengthy and highly variable process; a whole clove of garlic covered with vinegar can take from 3 days to more than 1 week to sufficiently acidify. As an alternative, properly dried garlic cloves may be safely added to flavor oils.

My goodness! I should have been extremely dead by now. Not as much by eating the confit cloves, they never last longer than a few days. The oil should have killed me and my family;  sometimes I use a batch for weeks in a row...

Ah well, ChaosPearl, back to the drawing board.

Your sarcastic logic is much the same as the logic used by a lot of guys I know that ride motorcycles without helmets. For me, I never know which motorcycle ride I take that might end in an accident, so I always wear a helmet. Play botulism roulette if you want. You may never get botulism, who knows?.

You're right cheflayne, I feel a warned person now, botulisme isn't exactly a joke...

No, Chris, it isn't a joke.

What it is, however, is the most overplayed card in the USDA/FDA hand.

Do some simple research about food-borne boutulism. What you'll find is that no insurance company would even keep actuarial tables on the correlation between boutulism and home-prepped/home canned foods. The risk levels just do not justify the hoopla.

Look at the garlic situation. All of the shouting resulted from just two events. And in the major one of those the problem stemmed from improper storage of the garlic-in-oil by a restaurant.

Everybody has to make their own decisions about things like this. But personally I wouldn't hesitate to eat garlic-in-oil that I had put up and stored in the fridge.

I used to work for a place that would reuse oil used to store peppers, olives, and a variety of deli salads. Honestly don't know how long or how many times the oils may have been used.  I do the same thing at home, I admit. I chopped too many aromatics.  Pack them in oil reuse them and have a wonderful byproduct that makes good salad dressing. But I'm assuming this "byproduct" may have been used up to a month after it was reserved. Is it me or is it a miracle they haven't killed somebody?

And Christ, I must say your photos are as amazing as your insight in whatever subject they're being used for.

Thanks KYH, that comment puts everything back into perspective.

Mostly when I make garlic confit, I keep the cloves in a plastic container as I showed in the pictures, with little to no oil and keep them in the fridge. The oil goes in a small bottle. I don't keep cloves in the oil which may reduce the botulism risk.

What about olive oil, which is more acidic than soybean oil?

Preserved vegetables (eggplants, carrots, peppers, etc) stored in oil with garlic and herbs are common here.  I steer clear of them, but have never heard of anyone getting botulism. 

Based on the USDA party line, Siduri, olive oil wouldn't make a difference. The "safe" acidic level is a maximum pH of 4.6. Anthing higher than that can support the bacterial growth.

Although olive oil is slightly more acidic than soybean oil, it's not enough to make a significant difference in the pH. Along with that is the density of the garlic. Again, based on the party line, garlic is too dense to "safely" absorb the acid anyway. But see my comments re: pickled garlic in the other thread.

Density is the same rationale USDA uses to recommend against pumpkin butter. Their claim is that you can't guarantee consistent heating of the center of the jar, even with pressure canning. Yet, in it's own study of pumpkin butter put up by a number of small, independent canners, not one of the tested jars met the 4.6 or lower pH test. So how come they didn't seek a recall of those "dangerous" jars? I mean, if they aren't acidic enough, and the heat levels couldn't be guaranteed, aren't those jars unsafe by definition?

Hi there.  Well, I have been storing garlic for years after I mince it.  I store it in plastic snap tight kinds of containers and I get a week out of it with no problem whatsoever.  It also doesn't hurt to mix in a little olive oil...  

Can i ask why you simmer the garlic in oil?and also you said you put the whole cloves in a container the fridge.Do you cover them in oil?Thank you for your post,cant wait to try this!

Why the drive to store minced garlic?  It's quick and easy to make fresh as needed and frankly, stored minced garlic flavor profile changes. Harsher, more sulfurous.  The flavor alone isn't worth the small convenience gained.

I'm a chef in the business 30 + years. I will get or peel whole cloves. Put in a small sauce pan and cover with oil( any kind). Simmer for 20 to 30minutes. The color will determine the time.Cool and strain .Save oil in a separate container and refrigerate the cloves.You can use the garl

ic whole and it will break down or you can make a paste with it. And you have infused oil also. 

Did you miss the original post? The author has severe arthritis and can't mince the garlic everyday. So she asked for help on how to store it, so she has minced garlic on her bad days.

My suggestion is to get a small "magic bullet" type food processor and pulse them fresh as needed. That way you don't need to store them. :)

Keep it inside a fridge and use it within 3-4 days

From what I am understanding, You should be able to use this device and place your previously made garlic confit in it and use your palm or fist to turn the top while the bottom half is resting on a damp towel to prevent it from slipping..

Another thought would be to use a grinder/mill if getting the blade cover on and off isn't too much of a task... One other thing to consider, and I know it is going to sound dumb but it may work... The slap chop... I would probably never use it for anything large or woody, but if you can make a fist to smack something, it might be worth it... They had small ones that you could probably use an elbow to hit... Keeping the thing stationary is another story... As I write this, I realize none of what I have said has had anything to do with the preservation the minced garlic but I'm hoping you find a way to manage.. I just keep thinking of all the ways I've seen garlic minced or smashed... Thinking of how Anne Burrell always uses her knife to smash the garlic, what if you were to find some sort of a weighted object that you fasten some form of elastic loop to that you could easily put your hand through and smash the garlic? Or softened/roasted garlic in a zip bag with a rolling pin?

Everyone thinks that the ability to grip a knife or squeeze two handles of something together is an easy task... I'm only 25 and can already feel that my hands aren't what they used to be and am worried what the next few years are going to bring... In the past year alone I've realized how much it hurts to grip a knife or wire whip...

I worked in a liquor store and had this lady that was a very good customer come in weekly.. I would look at her hands and just want to cry.. Her fingers were so twisted that they rested on the tops of the knuckles on the other fingers.. They were twisted 90 degrees...I felt so bad for her... She would always write a check and I could never understand why she'd do it... I asked her one day and she said it was one of the few things she could still barely do with her hands... She said the only reason she's able to still drive was because she could afford a car with the passive key system that didn't have to have the key in the ignition, you just pushed the button to start and stepped on the brake to slide the gear lever.. 

Anyways, I hope something I've said sparks something.. 

Good luck!

ChaosPearl  I hope this might help.  As  you can see from this thread there are safety considerations with prepping Garlic ahead of time but there are other ideas.  Target sells a product online called the Vibe from Chef'n.  It's basically a small ball with wheels and you drop the garlic in the top, roll it around and in seconds the garlic is minced.  Roll it less for coarse chopping and more for finely minced.  You can wash it in the top shelf of your dishwasher so clean up shouldn't be to difficult. Click on this link to have a look: http://www.target.com/p/vibe-by-chef-n-garlic-chopper/-/A-13682951#prodSlot=dlp_medium_1_1&term=chopper%20garlic  Other places have the same product, sometimes called the Garlic Zoom as well but prices vary pretty widely.  Good luck and happy cooking.
 

If I'm needing more than three or four cloves' worth of mince, I put the peeled cloves into my Cuisinart Mini-Prep and do a brief, pulsed whiz.  Nice thing is, that when they're the right size (a fine mince) the particles mostly stick to the sides of the bowl, away from the blades. It winds up an even mince.  I won't offer suggestions or opinions on preserving - I'm hoping this would be easy enough for you, ChaosPearl, that you could chop it as needed.

Cook's Illustrated offers a useful tip if you want some mellow taste of roasted garlic and some bite of raw - cook maybe 2/3 of your mince (I add some EVOO and use the microwave) and mix back with the 1/3 raw for some bite. I usually like the result unless I'm after a strong bite, then it's raw all the way. I'm a heavy-duty garlic freak; I swing that way pretty often.

Really hope the mini-prep idea (also advanced above) might help solve your problem.  Best wishes.

Mike

I agree with you.  When I need a whole bunch though for something to be eaten the next day, I sprinkle some Vitamin C powder on it (ascorbic acid).  You don't need a lot.  Botulism is something that starts in the soil, for those who don't know.
