Tarragon powder is a culinary herb made from dried and finely ground tarragon leaves. Tarragon is known for its aromatic, anise-like flavor with hints of licorice and vanilla. It's commonly used in French cuisine, particularly in sauces like Béarnaise, as well as in seasoning chicken, fish, and egg dishes. Tarragon pairs well with other herbs such as chervil, parsley, and chives.
