To prepare Diull Sauce: In a small bowl, stir together all ingredients until well mixed; cover and refrigerate until ready to serve. To prepare Tuna Croquettes: In a large bowl, combine tuna, eggs, potato flakes, onion, parsley, pepper and salt; mix well. Shape into 12 round patties, each about 1/2 inch thick. Place bread crumbs in a shallow dish. Completely coat each patty with bread crumbs. In a large skillet, melt 2 tablespoons of the butter over medium heat. Cook patties in batches 4 to 5 minutes on each side, or until golden brown, adding more butter to the skillet as needed. Serve immediately with Dill Sauce.
