Hah, for once, a benefit of having celiac, no wheat for me apparently means no weevils for me. I mix up a lot of gluten-free flour mix to substitute for all-purpose flour. It's a mix of way too many flours and starches (white rice, brown rice, sweet rice, potato starch, potato flour, ivory teff, tapioca starch, arrowroot flour) that I got from a blog many years ago, and haven't tried to slim down because it works great for me. Never had any bug issues; maybe specialty flours have better quality control.
I mix up 2 kilograms at a time: 500 grams sweet rice flour, 400 grams brown rice flour & potato starch, 200 grams ivory teff & arrowroot starch, 100 grams white rice flour, potato flour, & tapioca starch. The original recipe had almond flour instead of white rice flour, but I decided to make this nut-free (had some friends with nut allergies).
Nope - those are all bagged single ingredients I usually order online. Authentic Foods has most of them. The ivory teff is from Maskal. The arrowroot and tapioca might be called flour, starch, or powder - all the same thing. Potato starch and potato flour are 2 different things.
oh, so for example it's 100 grams white rice flour, 100 grams potato flour, and 100 grams tapioca starch, not 100 grams of a mix of the three? i guess that makes it add up to 2 kg
