3 cups buttermilk at room temperature
3 cups flour
1 tablespoon yeast dissolved in ¼ cup warm water (let it proof for 2-3 minute)
½ cup sugar
3 eggs, lightly beaten
2 teaspoons salt
5 cups flour, more or less
½ cup oil
1 teaspoon baking soda
Mix the buttermilk, flour and yeast/water mixture together thoroughly in a large mixing bowl. Let stand at room temperature until double in size, about 2 hours. Add sugar, eggs, salt, flour, oil, and baking soda. Mix well and knead for 7-10 minutes. Roll out the amount of dough you want and place the rest in the refrigerator, covered. The next time you want fresh baked rolls, take from the bowl what you want and again put the rest back in the refrigerator. It will keep for up to seven days.
Shape the dough into cloverleafs by rolling dough into small balls about 3/4-inch in diameter and place three balls in each cup of a greased muffin tin.
Let rolls rise until double in size, 1-2 hours. Dough taken from the refrigerator will take longer because the dough is cold. Bake at 350° for 10-12 minutes.
