Make sure that your fish is very dry before coating with sesame oil. Wrap snugly with 2-ply paper towels to remove any exterior moisture! Regarding the sliced fresh jalapeno peppers, use as many as you think you can handle with seeds either in or out, depending on how much heat you can handle. If you’re taste buds lean towards hot, and spicy flavors, you might want to add a drizzle of Sriracha over the fish.
