Mixed peel, also known as candied peel, refers to the peels of various citrus fruits that have been preserved and sweetened for culinary use. The most common citrus fruits used for mixed peel are oranges, lemons, and citrons, though other varieties such as limes and grapefruit may also be used.
The origins of mixed peel can be traced back to ancient civilizations, where the preservation of fruit peels was a way to extend their shelf life and make use of otherwise discarded parts of the fruit. Candied citrus peel production has a long history in Mediterranean Europe, and mixed peel in particular became associated with British and Italian baking traditions.
In modern cooking, mixed peel is primarily used as a flavoring and textural ingredient. The peel is typically cut into small strips or cubes and boiled in a sugar syrup to remove bitterness and infuse it with sweetness. The peel is then dried, often coated in additional sugar, to create the characteristic chewy, candied texture.
Mixed peel is commonly used in baked goods such as fruitcakes, mince pies, and Christmas puddings, where its bright, citrusy flavor and chewy texture complement the other ingredients. It is also used in some savory dishes, such as tagines and curries, where it can add a subtle sweetness and aromatic note.
Variations of mixed peel can be found in different cuisines around the world. In the Mediterranean region, mixed peel is often used in traditional pastries and confections, while in the Middle East, it is commonly used in rice dishes and stews. In India, mixed peel is a common ingredient in traditional sweets and is sometimes used to flavor tea.
When selecting mixed peel, it is important to look for high-quality, freshly made products that have a vibrant color and a balanced flavor, without an overpowering bitterness or excessive sweetness. Mixed peel can be found in the baking aisle of most grocery stores, as well as in specialty food shops and online retailers.
In terms of practical applications, mixed peel can be used in a variety of ways. It can be chopped and added to batters and doughs for baked goods, or it can be used to infuse syrups, liqueurs, and other beverages with its distinctive citrus flavor. Mixed peel can also be used as a topping for desserts, such as ice cream or yogurt, or as a garnish for cocktails and other beverages.
