Kydi,
If you run the almonds through your juicer again, you might have a suitable meal to use. The skins left on makes the product heavier, but usable. You might try blanching your nuts first to remove the skins. There are internet sites that show you how to do this. It does create a lighter flour from the almonds. Another thought is to look closely at the consistency of the meal that your health food store sells. If you can match it using your juicer, then that is fine. You might consider purchasing a food processor if you are going to be on a LCHF diet. This makes all those recipes a whole bunch easier.
Honeyville and Nuts.com sell the flour cheaper in bulk and have coupons for discounts, but you do have to pay shipping charges which are modest.
The meal is perfectly fine to use. I save my Honeyville flour for the baked goods which you might want a lighter result, like cakes or even the breads recipes from Dr. D's cook books.
