• Grains: Infuse rice or quinoa with citrus flavor by adding dried peels to the water during boiling/steaming. Peels may be eaten or removed before serving.
• Powder: Grind peels with a coffee grinder or mortar and pestle and sprinkle over baked goods (combine with sugar for sweetness), use in marinades and rubs, or anything else you can think of.
• Roasted vegetables: Although it isn't a substitute for fresh zest, dried lemon or even orange peel does work well in roasted dishes. Try tossing large pieces or ground-up peels with roasting beets and other root vegetables.
• Sweet bean soup: In Chinese cooking, Mandarin orange peels are added to sweet dessert soups. For recipes, check out A Table For Two's Red Bean Soupand Diana's Desserts' Sweet Red Bean Soup.
