Half-and-half is a dairy product made by combining equal parts of whole milk and light cream. It has a creamy texture and a fat content of about 10-12%, making it richer than milk but lighter than cream. Commonly used in coffee and tea, half-and-half adds a smooth, velvety taste without being overly heavy. It can also be used in cooking and baking, providing a creamy base for sauces, soups, and desserts.
