My maternal grandmother, the only real cook in our family, used to make salmon croquettes for me when I was a little girl, and I thought they were the best thing ever. She started with canned salmon, and mashed in some frozen mixed vegetables (peas, carrots, corn), plus bread crumbs to hold everything together. And an egg. If there were any spices besides salt and pepper, I'd be surprised. She pan-fried the croquettes in oil, the same way she made potato pancakes for Chanukah. When I had a craving recently for Grandma's salmon croquettes, I grabbed instead a can of tuna from the pantry, and found that I had most all of the ingredients for these patties in my pantry, too. My adult palate likes a little bit of heat, in the form of red pepper flakes, and the extra crunch of panko bread crumbs (though you could certainly use regular bread crumbs, or even gluten-free crumbs). I've swapped fresh vegetables for the frozen peas and carrots, but in spirit, these are the croquettes my grandmother used to cook for me. Make them small, for appetizers, or larger patties, for a lunch or light supper main dish.
