What Is Homemade Horseradish Made Of?
Homemade horseradish is typically made of grated horseradish root, vinegar, water, and salt. Some recipes may also include ingredients like sugar, lemon juice, or mustard. The sharp and pungent taste of horseradish comes from a compound called isothiocyanate, which is released when the root is grated or chopped. Homemade horseradish can be used to add flavor and heat to a variety of dishes, including sauces, marinades, and dips.
