I also made some raspberry muffins. We have a huge raspberry bush in the yard and I could not wait for them to be ripe enough to use!
Here is a great recipe for the muffins.
The first stage of preparation in making whole grain porridges or baked recipes, is to soak the whole grains or whole grain flour in an acid medium such as buttermilk, yogurt, or other cultured milk, or in water with whey, lemon juice or vinegar added. As little as 7 hours soaking will neutralize a large portion of the phytic acid in grains. Twelve to 24 hours is even better with 24 hours yielding the best results- Sue Gregg) BTW, I do this for our whole grain pancakes, our rices and grains as well. A little effort will be worth it!
