I like to open my cookbook, choose a recipe, and substute in acceptable ingredients.
EXAMPLE: all-purpose flour (use coconut flour, or maybe millet flour), sugar (use zylitol or stevia), vegetable oil (use olive oil or coconut oil, or another cold-pressed type of oil listed in the approved foods), shortening (use organic butter, ghee, or coconut oil if it doesn’t need to be a solid fat), carrots (use zuchini), etc.
I haven’t found a good substitute for fruit, however. 🙁
Good luck! And post if you find a really yummy one!
