tea
Tea is a rich source of polyphenolic antioxidants, particularly catechins in green tea and theaflavins in black tea. It contains caffeine (typically 25-50 mg per cup depending on type and brewing) and L-theanine, an amino acid that promotes relaxation.
About
Tea is a beverage made by steeping the leaves of Camellia sinensis, an evergreen shrub native to East Asia, in hot water. Despite the diversity of tea types consumed worldwide, all true tea derives from this single plant species; variations in color, flavor, and oxidation level result from different processing methods applied to the leaves after harvesting. The plant produces amino acids, polyphenols, and caffeine compounds that contribute to tea's characteristic taste and bioactive properties. Major tea-producing regions include China, India, Japan, and Kenya, with distinct regional cultivars and terroirs influencing the final product.
Culinary Uses
Tea serves as a beverage consumed worldwide and as an ingredient in both sweet and savory cooking. Beyond drinking, tea is infused into desserts, creams, and baked goods—particularly matcha in Japanese confections and strong black tea in British cakes. In savory applications, tea brines meat, seasons stocks, and flavors Asian soups and rice dishes. Tea's astringency, earthiness, or floral notes complement delicate proteins like fish and poultry, while robust varieties pair with rich foods. The brewing time and temperature significantly affect flavor extraction and should be calibrated to the tea type for optimal results.
