Has Anyone Made and Baked with Their Own Coconut Flour or Sunflower Seed Flour?

I haven't done it, but I have to say it sounds like a huge amount of work. By the time you take a fresh coconut and separate it, then grind your own flour, I can't imagine it's cheaper on a small scale than it is in a large scale processing plant. It's at least as expensive to ship and store fresh coconuts to areas where they don't grow naturally, than it is to process them elsewhere and ship you the flour.

You don't say why you want to eliminate most grains, but usually it's easier to put into your diet those elements that enable the body to process the ingredients that most of us can eat every day. I work with a lot of people who've done just that, reducing or eliminating food sensitivities.

i bake with coconut flour all the time but just the one from the store , you can find some brands where it says that they were not manufactured near nut products ….

Go to a health food store, if you calculate how many servings are in a bag, and the price per unit, you're probably better off buying it. The only way I can think to make it is with a coffee grinder (I used to grind flax seeds that way).

I've purchased alternative flours at a grocery store. Some alternative flours can be bought in bulk. Yes, they're more expensive but not by much. These flours are stone ground. My aunt had a stone grinder. They are expensive. I suggest that you won't be able to grind the flour fine enough using a blender or coffee grinder.

These flours have no gluten which allows the product rise. Unless the flour is ground fine I suggest that the product will be too dense. Also you have to use special recipes. The ones that use wheat flour will not work.

Also there are many different flours: rice, soy, corn, etc. Many recipes use a combination of different flours. So it's not just substituting one flour for wheat flour.

I also suggest that by the time you buy enough of an ingredient to make enough flour to use you will be spending near the same amount.
