Sourdough Teff Gingerbread

Combine and let sit 24 hours:

1 cup teff flour
1 1/2 cups boosted brown rice starter

1 egg, separated, whites beaten till stiff
1/4 cup olive oil
2 tbsp. grated ginger
1/4 cup honey (more if you like it sweet...) OR 1/2 cup sucanat
1 tsp. baking powder
1 tsp. cinnamon
1/2 tsp. salt
1/2 tsp. nutmeg (optional)
1/2 tsp. allspice
1/8 tsp. cloves (optional)

I baked at 425f in a nine-inch pie pan for about 40 minutes, but the top was a little overdone. Maybe a lower heat? Or bake as muffins?
