It took me awhile to get this right...I really like the chili powder in this recipe.
1 1/2 cups rice flour
1 cup crushed rice cereal (can be omitted)
1/2 cup potato flour
2 tsp. baking powder
2 tsp. salt
2 tsp. chili powder (or more to taste)
Sift all ingredients until well blended. Store in an airtight container in a cool, dry place. Use quickly or store in the refrigerator for longer shelf life.
