The main difference between peppermint and mint extracts is the plant from which they are derived. Peppermint extract is made from pure peppermint oil, while mint extract is derived from any number of, or combination of, culinary mint plants.
Peppermint and mint extracts flavor candies, cookies, cakes and other baked goods. They are also used in dressings, teas, fruit dishes, marinades and vinegars. Peppermint and other mint extracts are interchangeable in recipes, though the flavors are different.
Imitation peppermint and mint extracts use artificial flavorings to create the taste of pure extracts. Imitations do not contain the same benefits as pure extracts and are often milder in flavor.
