The Wonder Wheels

It sounds like you are referring to "whelks," which are a type of edible sea snail that are sometimes served in restaurants, including in the United States. Whelks are a type of mollusk, and are related to other seafood such as clams, oysters, and mussels.

Whelks are often served cooked, and can be prepared in a variety of ways. They can be boiled, steamed, grilled, or fried, and are often served with butter or a dipping sauce. In some cases, whelks may be served raw, although this is less common due to food safety concerns.

Whelks are a good source of protein, and are also low in fat. They are also a good source of several vitamins and minerals, including vitamin B12, iron, and zinc.

If you are interested in trying whelks, you may be able to find them at a seafood restaurant or specialty food store. Keep in mind that they may be called by a variety of names, including "sea snails," "whelk clams," or "knobbed whelks." It may also be helpful to ask the restaurant or store for recommendations on how to prepare and eat them.
