Place onion, garlic and celery into a food processor and blend for 7 or 8 pulses. Preheat skillet on medium heat and melt butter.

Dump vegetables into a good sized mixing bowl.
Gently press crabmeat against fine strainer to remove as much milk as possible without destroying any lumps of crabmeat. Discard milk.
