How much ingredients do you put in salmon patties?

To make salmon patties, you'll typically need about 1 can (14-15 ounces) of salmon, 1/2 cup of breadcrumbs, 1/4 cup of finely chopped onion, 1/4 cup of chopped fresh herbs (like parsley or dill), 1 egg, and seasonings such as salt and pepper. You can adjust the quantities based on your taste preferences or the number of servings desired. Additionally, you might add ingredients like mustard or lemon juice for extra flavor.
