Heat oil to 325 degrees.
In one mixing bowl blend together all dry ingredients. In a separate bowl, whisk together the egg and milk. Gently fold the dry ingredients in to the milk mixture. Gently fold the crabmeat and red onion into the batter.
Drop 1 tablespoon of mixture into the hot oil at a time. Fry until the puffs are golden on all sides.
Remove and drain on paper towels. If needed, hold the puffs in a 200 degree oven until service (no longer than 25 minutes).
Serve alongside Pepper Jelly Dipping Sauce
