2 cups whole wheat flour or whole wheat pastry flour
1 Tbls baking powder
1 tsp. cardamom
1/2 tsp. salt
3 Tbls. brown sugar or honey
1 Tbls. oil
3 egg whites
1/2 cup yogurt
1 cup chopped plums (fresh, dried, or preserved. If using preserved, omit the sugar/honey)
Preheat oven to 400 F.
Stir together the flour, baking powder, cardamom, salt, and brown sugar/honey. Stir in the oil, then stir in the egg whites. It should be a dry crumbly mixture. Stir in the yogurt and plums together.
Sprinkle flour on your baking sheet. Turn out the dough onto the baking sheet and knead lightly to form it all together. Form into a smooth, thick circle. Brush the top lightly with egg yolk. Cut into 1/8 wedges. Gently pull them apart so they're not touching. Bake for 15 minutes.
