Prepare the Salmon: In a medium bowl, add the drained canned salmon, breaking it up with a fork.
Mix in Ingredients: Stir in the finely chopped onion, cornmeal, flour, beaten egg, salt, and pepper until well combined.
Shape the Patties: Form the mixture into small patties, about the size of your palm — this should yield roughly 6-8 patties.
Heat the Oil: In a frying pan, heat about 1/2 inch of oil over medium heat.
Fry the Patties: Gently place the patties in the hot oil and fry until golden brown and crispy, roughly 3-4 minutes per side.
Drain Excess Oil: Remove patties from the pan and let them drain on paper towels.
Serve Hot: Serve your delicious salmon patties warm with your choice of dipping sauce.
