A crosne is a pale white tuber that is eaten in many parts of the world. It is native to Asia and tends to be most popular there, but it will grow well in most moderate climates. Many people compare its physical appearance to insect larvae or fat caterpillars, and it is often said to taste a lot like raw artichoke. Crosne is a versatile food that can be enjoyed in a variety of ways, though it is most commonly sauteed, fried, pickled, or steamed.
Crawfish, sometimes called crayfish, are similar to lobsters but much smaller. Crawfish are most commonly found in Louisiana, and they are eaten there as a part of southern cuisine, or Cajun cooking. Crawfish are tender and usually boiled but they need to be cleaned first, which is referred to as purging.
