Salad salad (a noodle-based salad). The sauce used to flavor a salad is commonly called a salad dressing; most salad dressings are based on either a mixture of oil and vinegar or a fermented milk product like kefir. Salads may be served at any point during a meal: The word "salad" comes from the French "salade" of the same meaning, from the Latin "salata" (salty), from "sal" (salt). In English, the word first appears as "salad" or "sallet" in the 14th century. Salt is associated with salad because vegetables were seasoned with brine or salty oil-and-vinegar dressings during Roman times. The
Mustard (condiment) glucosinolates in mustard plant varieties, and the different isothiocyanates that are produced, make different flavors and intensities. Prepared mustard condiment may also have ingredients giving salty, sour (vinegar), and sweet flavors. Turmeric is often added to commercially prepared mustards, mainly to give them a yellow color. Prepared mustard is sold in glass jars, plastic bottles, or metal squeeze tubes. Because of its antibacterial properties, mustard does not require refrigeration for safety; it will not grow mold, mildew, or harmful bacteria. Mustard can last indefinitely without becoming inedible or harmful, though it may dry out, lose flavor, or brown from oxidation.
