     1/2           cup  unbleached white flour -- prefer pastry flour
     1/2      teaspoon  baking powder
  1 1/4           cups  sugar -- or more to taste
  1 1/2           cups  buttermilk
     1/2           cup  fresh lemon juice -- (about 4 1emons)
  2                     egg yolks -- lightly beaten
  2          teaspoons  lemon -- (opt) freshly
                        -- grated
  4                     egg whites
                        --pinch of salt

Preparation:

Preheat the oven to 350 degrees. Prepare six 8-ounce ramekins or ovenproof dessert cups with a very light coating of cooking spray or oil. Place the cups in a 2-inch-deep baking pan. Begin to heat a kettle of water to a boil. In a large bowl, combine the flour, baking powder, and 3/4 cup of the sugar. (If you want a very sweet confection, use a whole cup of sugar.) Stir in the buttermilk, lemon juice, beaten egg yolks, and the grated lemon peel, if using, and set aside. With an electric mixer, beat the egg whites and salt until the whites are stiff. Beat in the remaining 1/2 cup of sugar. Gently fold the egg whites into the batter. Spoon the batter evenly into the prepared cups. Pour boiling water into the baking pan until the water reaches halfway up the sides of the cups. Bake for 50 to 55 minutes, until puffy and golden.
