Is Unagi Sauce Gluten-Free?

The simple answer to this question, “Is Unagi Sauce gluten-free?” is no. Most brands of Unagi sauce usually contain soy sauce, which is traditionally made with wheat and is therefore not gluten-free. However, there are gluten-free options available where tamari (a type of soy sauce made without wheat) is used instead of traditional soy sauce. Always read labels and information to ensure a product meets your dietary needs.
