Preparation Mix sake, mirin, and soy sauce into a small bowl (this is the teriyaki sauce). Heat one tablespoon of vegetable oil in a large skillet over medium-high heat (add more more oil if needed). Salt salmon, and cook it skin-side down for about 4 minutes; then cook other side until meat begins to brown.
Remove fish from the skillet and pour 2/3 of the teriyaki sauce into pan. Heat until it begins to boil. Add salmon fillets skin-side up and pour the remaining 1/3 sauce over the top of fillets. Cook for 2 minutes and your teriyaki salmon is ready to eat!
