So, how long do you actually boil a live crab? Well, as I mentioned earlier, it's about 8-10 minutes per pound, but this can vary depending on the size and species of your crab. For example, a Dungeness crab might take a bit longer to cook than a Blue crab, so be sure to check on it regularly to avoid overcooking.

And don't even get me started on the importance of monitoring the temperature! You want to keep the water at a roaring boil, but not so hot that it scorches the crab. It's a bit of a balancing act, but trust me, it's worth it in the end.
Now, I know what you're thinking: what about the poor crab's feelings? Don't worry, I've got a crab-friendly solution for you! You can actually anesthetize the crab before boiling by submerging it in ice water for about 30 minutes. This will put it right to sleep, and make the whole process a lot more humane.
