Almond flour is great for low-carb baking. Haven’t tried making a pit crust, but you probably could.
Yup. Almonds work well.
We have been low carb for two and a half years. I lost 55 lbs, my wife about the same. Best of all we have kept it off.
I have used almond flour in snowball cookies but find it denser than regular flour. You might want to try a blend to keep the crust a little lighter. I think I did use about half regular and half almond but will try a quarter of almond next time. Of course, cookies aren’t quite the same as pie crust but maybe a little experimenting would be useful. Pie crust cookies would be an easy way to experiment without committing to a pie.
