I eat a Keto diet, when I first started out I experimented with a wide variety of recipes that used almond flour and I was disappointed in 99% of them. I decided it wasn’t worth the effort or expense and decided to just cut it all out! This means no sugar and no flour substitutes at all, they all end up horrid, the same can be said for coconut flour etc. . YMMV as everyone has different tastes.
