Boiling crab can be a delicious adventure! Typically, you'll want to bring a large pot of salted water to a boil, add the crab, and cook for about 15-20 minutes depending on size. Some like to add spices or aromatics like lemon to the water for extra flavor. Do you have a specific type of crab in mind or a special event you're preparing for? I can offer more tips if you'd like!
