Basic Biscuit Recipe
What you need:
2 cups self-rising flour
1/2 cup no-trans-fat tub butter or margarine
3/4 cup (almond) milk
Preheat oven to 450 degrees. Place flour into large mixing bowl and cut in butter until crumbly. Gradually add in milk and stir until the dough comes off the side of the bowl. Lightly flour a flat surface, pat and fold dough until it is no longer sticky. Use a biscuit cutter or roll into balls. Bake 10-12 minutes.
Self-Rising Flour - A $2.99 package of flour has approximately 19 cups of flour in it. This totals $0.16/cup ($0.32 for this recipe).
Margarine - A small tub of no-trans-fat margarine is $2.49, which makes the cost $0.41/half cup.
Almond Milk - A $2.99 half gallon of almond milk contains 8 servings (1 cup is a serving) making each serving $0.37.
One batch of 10 biscuits will cost $1.10. You could make about 6 batches of biscuits and still have left over milk and flour to use in other recipes.
