When we are up North in our caravan, we steam mud crabs in a big pot with a cake stand in it. The cake stand keeps the crab out of the water. obviously, your crab would have had to be dead to cook it in the Varoma, or it would have eaten it . Did you put it in the freezer for a while to kill it, or did you pierce the brain. I must try this with my TC when we go away this year. Steaming is definitely better than boiling it, as it tends to fill up with water when boiled.
