Half-and-Half is a dairy product that consists of equal parts of milk and cream. It is commonly used in coffee and tea as a creamer, providing a rich and smooth texture without being as heavy as pure cream. This versatile ingredient can also be used in cooking and baking, adding creaminess to sauces, soups, and desserts. It typically contains about 10-18% fat, making it a popular choice for those who want a lighter alternative to heavy cream while still enjoying a creamy flavor.
