Red Seal Cook

Answer: B - It takes roughly 5-10 minutes to fully cook a crab weighing 1kg using the simmering method. This timing may be applied to any weight- for example, a 2 kg crab would take roughly 20 minutes to cook, a 3kg crab would take between 25-30 minutes, and so on. When crabs are fully cooked, their shell will turn a bright red color. Overcooking can result in tougher meat so it’s good to keep an eye on the clock as well as on the color of the crab itself.
