Quote Normandie; I have some home grown recurrants in my freezer which I plan to make some redcurrant jelly ( love it with roasted lamb - its a Brit thing) Do I need to top and tail them before cooking them?
Each year I collect a lot of elderberries. A little similar to redcurrants in making jam or jelly. This may help, although there might be other methods.
I wash the fruit and take the berries from their stalks, which goes easy, just takes a lot of time. Then I cook them without sugar until soft, let cool a while and then pass them through a food mill using the finest sieve. All seeds etc. remain in the foodmill.
Please note that the fruit is cooked with no sugar in this stage, but I add the juice of 1/2 lemon per liter of juice and store the mixture away for a whole night. I always add lemonjuice in jams/jellies. It improves the taste dramatically, even when using sour fruits! Also helps the pectine to do it's work.
Only the next morning I proceed in my odd but very effective way;
- heat the oven at 110°C - put the sugar in an oventray and cover with an ovenplate - put in the lower part of the oven
- wash jars and put still wet, upward in the oven on another ovenplate- the jars dry and sterilize during the time you need to cook the jam. Also, pouring boiling hot jam in it will never cause them to break. One thing; don't put the lids in the oven!!
- heat the fruit gently to the boiling point
- carefully (very hot) take the sugar from the oven and pour in the fruit. This will bring the whole mixture to a boil very quickly! And strangely the jam will produce almost no scum at all.
- when the jam is done, immediately take the hot jars out of the oven, a few at a time, immediately fill with boiling hot jam, cover and put upside down on their lid.
- leave on their heads untill you can handle them, don't leave to cool entirely on their head.
I now still have a small batch of elderberry jam that's... 2 years old, still in perfect shape and delicious. I notice that the jars are very tightly closed the way I make them. Takes a lot of force to open them.
