Now, it’s the step to prepare the salmon patties. Take a bowl to combine salmon, chopped onions, breadcrumbs, egg, parsley, mayonnaise ( 2 tablespoons), lemon juice ( 2 tsp), and dry mustard together. Mix all the ingredients until it becomes smooth.
If required you can add breadcrumbs in the mixture to avoid extreme softness. After that consider seasoning it with salt and pepper. When everything gets mixed up properly, shape the dough into 6 patties.
