Marinate salmon in a plastic bag or bowl with 2 tsp ginger, 2 Tbsp mirin, 2 Tbsp soy sauce, and 1 ½ Tbsp rice vinegar for 30 minutes.
Place marinated salmon and any sauce in baking dish and cook uncovered ~ 15 minutes depending on thickness or until fish is flaky.
Bring a small saucepan to medium high heat and whisk in glaze ingredients (3 Tbsp soy sauce, 2 Tbsp Honey, 1 ½ Tbsp fresh lime juice. Bring to a boil and simmer uncovered ~ 5-7 minutes or until sauce is thickened. Stir often so that the honey does not burn or separate.
Add 1 Tbsp water to wasabi powder. Stir in more water one teaspoon at a time until it reaches your desired thickness. Set aside.
Plate salmon with sauce from baking dish. Add glaze and add a dollop of wasabi for some heat. Happy eating! Beckie
Notes
Don't have mirin? Use rice vinegar instead with 1 teaspoon of sugar.
You can also marinate up to 24 hours in advance.
Wild salmon generally cooks faster than farmed salmon due to it being thinner and less fatty. Adjust your cooking time if you've got a thin fish fillet.
