I agree that it's not the same as fresh crab meat but I have substituted with tinned to make a simple crab linguine.
While you cook the linguine, fry garlic and chilli in olive oil, being careful not to burn the garlic then stir in the crab meat.
Drain pasta and reserve a little water, toss into the crab and chilli sauce. squeeze in some lemon juice, add a little of the pasta water to loosen the sauce if needed.
Season and chuck over some chopped parsley to finish.
I love this although i must stress it is a million times nicer with fresh crab meat.
