Sprinkle salmon with salt and pepper; press salmon into seeds. Place skin side down on buttered, foil-lined baking sheet. Bake in 450F oven for 10-15 minutes or just until white juices appear.
In a large skillet, melt butter over medium-high heat. Saute onions and ginger until soft, about 5 min. Stir in vinegar until evaporated. Stir in cream, bring to a boil for two minutes, stir in salt and pepper.
Spoon sauce on serving plates and top with salmon fillets.
Notes
Rice or steamed vegetables make an excellent side dish.
