Sauce was eyeballed with diced cilantro, diced garlic, diced ginger, soy sauce, sesame oil, 1 T sugar, juice from 1/2 a lime, and a dash of olive oil.
Tuna steak was seared in a SMOKING HOT cast iron skillet in peanut oil for 15 seconds per side.
Served with sliced avocado, and additional course fresh ground sea salt and pepper.
Original recipe I based this on called for diced jalapeno too, which I didn't have. Next time, I would serve with paper-thin sliced serrano peppers as a garnish, and a sprinkle of sesame seeds as well.
Then............ it would be perfect.
