Feel free to add herbs and spices to give these an added flavor. Cheese and chili pepper come to mind. Serve with butter, jam, a stew, or just about any meal. They will deflate after several minutes of being out of the oven, but they still look and taste marvelous. These are meant to be eaten when fresh out of the oven, but you can store them at room temperature for a few hours if necessary. Also note that I use these muffin liners so the popovers don’t stick to the liners. Or try silicone cupcake/muffin molds.
