A cook prepares a dish for a guest with a wheat allergy. Which ingredient must be avoided because it contains wheat?

解析

Regular flour tortillas are made from wheat flour and must be avoided for a wheat-allergic guest, while handmade corn tortillas, plain grilled chicken, and plain steamed white rice are wheat-free as long as no sauce or breading is added. Managers should teach staff which menu items and substitutions are safe. Reading labels and recipes helps catch hidden wheat in breading, sauces, and thickeners too.
