I did some alt flour experiments a while back. May give another try. 

 Flirting with keto? Honestly, when I did that, I’ve been disappointed by all those keto substitutes I tried. Some are ok, some resemble the original non-keto food somehow, but none come even close to the flavor and texture of the real thing. 

Not that they are bad, but when I expect to eat a pizza, the chewy, airy pizza crust, the taste and smell of that fermented dough makes up most of the sensorial experience. A keto pizza will never be a pizza, even if it’s delicious nonetheless.

It’s much more rewarding finding new real delicious original keto recipes and not trying to resemble non-keto food that you love, because it’s very likely it will end in disappointment and going back to the real thing eventually.
