Sitting at our sons’ lacrosse game, my friend, Christina, told me about a marinade that she had recently used on swordfish. When the evening’s plans went awry and she had to save the already-marinating swordfish for the next night, she realized that an overnight marinade worked quite well with this recipe.
She was kind enough to share the recipe and I tried the overnight soak, too. It was fantastic! If you haven’t thought that far ahead, however, a few hours will impart great flavor, too. I also thought this marinade would be exceptional for tuna topped with wasabi sauce. A ripe avocado initially inspired this sauce which has become a favorite in our house. Don’t limit it to just tuna; spoon over salmon, mash into a baked potato, or dollop over steak!
