Salmon Croquettes Drain cans of salmon, reserving the juices in a separate small bowl. Place salmon in a large mixing bowl. Carefully remove the skin and bones from salmon and discard. Mash salmon until smooth and pieces are broken up. Add the onion, eggs, matzo meal and 2 tablespoons of the reserved salmon juices (or more to taste). Mix to blend until consistency is a mostly smooth batter. Season to taste with kosher salt and freshly ground black pepper. Using your hands, form patties from the mixture (about ¼”-1/3” thick). Add enough additional oil to the reserved skillet to bring the level of oil up to 1/3” depth. Heat oil in skillet over medium-high heat until oil is hot. Carefully place patties in skillet and fry until nicely browned, turning only once – about 3-5 minutes per side. Do not overcrowd pan. Remove croquettes and transfer to a large platter lined with paper towels to drain. Repeat with remaining patties. Serve hot, topped with fried onions and enjoy. Fried Onions Add a generous layer of oil to cover the bottom of a large skillet (about ¼” depth), and place over medium heat for a few minutes until the oil is hot (you can test this by adding one piece of onion – if it sizzles upon contact, then the oil is hot enough). Add the sliced onions and cook, stirring occasionally, for about 15-20 minutes or until the onions are golden brown. Remove skillet from heat. Remove onions with a slotted spoon and transfer to a plate lined with paper towels to drain, reserving cooking oil in pan.
