Open the can of salmon and drain really well. You can remove the skin and bones if you like but Mom never did and I don't either.

In a bowl mix the salmon, egg, onions, and cracker crumbs. Be sure you mix really well. The finer the mixture the less likely your patties will fall apart when cooking.

Form 6 patties.

In a frying pan, heat the oil and butter until the butter is melted.

On medium heat, fry the patties 5 minutes per side, or until golden brown.

You may need to add more oil and butter.
