This is an old recipe, but its classic...I don't think anyone can claim it. I adapted it slightly.

Popovers!
1/2 cup brown rice flour
1/2 cup sweet rice flour (or pretty much any flour or combo)
1 cup water (milk if you can tolerate it)
1-2 eggs

Beat the eggs in the water. Gently fold in the safe flour. Put 2 TBS in each mini muffin tin space. Bake at 350ish until they pop (20-30 minutes) I like to err on the over cooked side...dh likes things part raw.

A little sugar goes nicely in there too.
