of lemon peel or 2 spoons rum

Lemon peel, also known as lemon zest when finely grated, is the colored outer rind of the citrus fruit Citrus limon. This thin, oil-rich layer contains the fruit's essential oils and aromatic compounds that give lemons their characteristic tart, bright flavor. The peel is typically yellow when ripe, though green varieties exist in unripe lemons. The inner white pith beneath the colored zest is bitter and is usually removed for culinary purposes. Lemon peel contains significantly more aromatic compounds than the juice, making it a potent flavoring agent in cooking.

Lemon peel is used to impart bright, citrus flavor to both sweet and savory dishes without adding the acidity of lemon juice. It is commonly grated or zested over pasta, seafood, baked goods, and salads, and is a key component in marinades, dressings, and spice blends. Candied or preserved lemon peel is used in confections, marmalades, and baked goods. In cocktails and beverages, expressed lemon peel oil adds aroma and flavor. The peel pairs well with herbs like basil and oregano, and with aromatics such as garlic and thyme.
