Lobster mushrooms are a real treat of a wild mushroom. They're dense and meaty and taste great. Although they don't taste a lot like ocean lobsters, they do often have a seafoody smell. Some people say that the mushrooms taste slightly of seafood, but in general, they're mild and slightly sweet. Their name comes from the uber-brilliant cooked-lobster shell coloring and the strong seafood scent that develops when they're past maturity.
