We (my family) was thinking of trying to market simple mixes for simple baked goods like muffins, probably for the UK. I know making from scratch is every bit as easy as a mix, but many people think it's impossibly difficult. My daughter thinks these might have a market there, that they could be made through an existing bakery or food plant, and I'm the one who is supposed to work on the formula.
I was thinking they should be simple, without preservatives and where you add milk, eggs, butter (yeah, i know, it's ridiculous, because the rest is just measuring sugar and salt and baking powder, but yet people seem to particularly like mixes where you add these ingredients yourself. And that would avoid all the crappy additives, fake shortenings, etc.)
What i wanted to know is anyone has done this, if anyone knows if flour, cornmeal, oats, bran, dried blueberries, cranberries, raisins, baking powder, baking soda, salt, etc, need any special treatment to be kept for a year, say, in a normal package. I;d work on a recipe that can add the liquid ingredients all at once.
