There are a variety of gluten-free pastas available. Most are made of corn, rice, quinoa, or buckwheat. Since these pastas lack wheat, which acts as a binder in traditional pasta, they cook differently and can get mushy quickly if overcooked. Reference the package when cooking each variety because cook times and procedures for the best results vary.
