Crawfish is basically like a tiger prawn crossed with a more solid head like a lobster but since we ate it at the start of the season they were much smaller as well. A crawfish boil is a typical Louisiana dish and is usually done in a large pot fitted with a strainer and lots of seasonings including cayenne pepper, hot sauce, salt, lemons and bay leaves. Ears of corn, new potatoes, onions, and heads of garlic are usually included and some people will add smoked sausage links or mushrooms but ours was just pure crawfish, corn and potatoes. They are pretty fiddly to eat but the spices tasted so good!
