To make this Sichuan Hot and Sour Soup gluten-free, use tamari or a certified gluten-free soy sauce in place of regular soy sauce. Always double-check that your chicken broth and vinegars are gluten-free, as some brands may contain additives derived from wheat. The rest of the ingredients — tofu, mushrooms, bamboo shoots, and spices — are naturally gluten-free. With these substitutions, you can enjoy the same vibrant, tangy-sour flavor without compromise.
