小贴士
For sweet, cinnamon-sugar popovers: Prepare and bake the popovers as instructed. When the popovers come out of the oven, brush them with melted butter (about 1/4 cup per batch), and roll them in cinnamon-sugar (about 1/4 cup per batch).
For savory, cheddar-herb popovers: Mix 2 teaspoons herbes de Provence and 1/4 cup Vermont cheese powder to the flour before stirring it into the sourdough-egg mixture. Finish the popovers according to the recipe instructions.
