What is tomale in a lobster?

There is no part of a lobster called a "tomale." It's likely a misspelling or a word that doesn't exist in the context of lobster anatomy.

Perhaps you were thinking of a different part of the lobster, like the tomalley, which is the green, pasty substance found in the lobster's head. It's the lobster's liver and pancreas, and some people consider it a delicacy.

If you can provide more context or clarification, I might be able to help you further!
