In the recipe that follows for Chocolate and Orange Swirl Muffins, the batter is divided into two batches, each differently flavored, which are then put into the muffin C. in alternate spoonfuls to produce a beautiful swirled effect that reminds me of that kugelhopf my sister and I used to make. Chocolate chips in both batches are an extra treat. Of course, you could also add or substitute your favorite chopped nuts for the chocolate; or use different flavorings, such as lemon zest or vanilla or sweet spices.
