I don't know, I woke up and realized that I could put stuff in vodka and it's probably better than the extracts I buy. I started by putting the kernels from peach pits in a 1/2 cup of vodka (I don't go through almond extract all that quickly!). Apparently the kernels, the soft inner part of the pit from peaches and apricots, taste like almond extract. We shall see. The jar is tucked away for several months in my spice cupboard. I followed these directions.
And then I talked to a coworker who makes his own vanilla extract and went straight to Ebay and ordered vanilla beans from Uganda. Now I'm going to make vanilla extract.
I don't know if this is cheaper, exactly, than buying vanilla extract, but I'm betting it will taste better. I like to think I am clever with my food money, spending money where it makes a difference in taste, nutrition, and the environment. Sometimes, all three line up, like now when the local veggies and fruits are pouring in from the careful farmers who are not certified organic, but just farm that way because it makes sense to them. And me.
