Dissolve one package quick-acting yeast and a tablespoon of sugar in a half cup each of warm buttermilk and water. When the yeast begins to work, add a quarter cup of vegetable oil, and blend in a mix of three cups flour (this loaf was made with Martha White), half a cup of grated sharp cheddar, and a quarter cup of fresh rosemary leaves. Knead until smooth, let rise for three hours, punch down, and place in an oiled baking pan to rise until doubled. Bake in a moderate (350) oven until crisp and golden. Brush loaf with butter.
