Hi Steve,
A great hamburber bun recipe is this :
500 g flour - unbleached, whole wheat, or a mixture of the two
4 Tablespoons powdered milk
4 Tablespoons sugar
4 Tablespoons oil
1 Tablespoon yeast
1 Tablespoon Baking powder
1 teaspoon salt
1 1/2 cups water
Mix all. Knead well. Let proof until doubled. Divide into 12-14
portions. Shape (this is very important as your final product will
look better, the better your shaping technique). Let proof until
almost doubled and slightly squish with the back of a spatula, so
they don't come out round like a dinner roll.
You'll get a soft and light bun from this recipe, and don't forget to
spray with water and sprinkle with sesame seeds before baking.
Cheers,
Sam.
