Mustard
There are many types of mustard, including the well-known English, French, and Dijon mustards.
These are often used in salad dressing, including mayonnaise and vinaigrette. They are also common in cheese dishes and ham sandwiches.
The mustard and cress many of us grew on top of a potato or eggshell as children comes under this category. This can also cause an allergic reaction in a mustard-allergic person. Therefore, if this is used in a salad or in an egg and cress salad, it is important to mention this in the ingredient information.
