BaoZi (Chinese Steamed Buns)

A common Chinese lunch or breakfast snack
1 dozen buns

    3 cups bread flour
    2 teaspoons sugar
    1/2 teaspoon salt
    2 teaspoons salt
    3/4 cup water
    1 tablespoon peanut or vegetable oil
    1 large egg
    filling: Red Bean, Pork or Chicken
    sesame seeds

Mix all ingredients. Let rise about an hour, punch down, and let rise again until doubled in bulk. Knead. Divide into 12 equal pieces. Roll into 4 inch round. Place the dough in the palm of your hand and fill with 1 tablespoon filling. Gather up the sides around the filling and twist the dough to seal. Place, twisted side down, on a piece of aluminum foil. Cover and let rise in a warm, draft-free place about 15 minutes. Place the buns on the foil on a steamer rack over boiling water. Leave at least 1 inch free space between the buns. Cover and steam 15-18 minutes, until done. Sprinkle each bun with sesame seeds if desired.
