Cinnamon is hands down the most traditional spice for seasoning applesauce (and a wide variety of other apple creations, both sweet and savory), but cardamom is equally delicious with the fall fruit, though less familiar by far, and its singular flavor also marries well with cinnamon. Try this simple applesauce recipe for yourself to see, pureeing the sauce if a smoother constistency is desired, or mashing a bit for a chunkier texture.
