This is a simple recipe for a Tuna Steak, inspired by a Jamie Oliver recipe.
Roughly grind up fennel seeds, pepper and coriander seeds with salt. Massage it into the fishes along with some olive oil.
Get a girdle pan to high heat. Carefully place the fish on it and let it sizzle and steam away. About 3-4 mins later check if the fish is able to free itself from the pan. If it does not encounter resistance, flip it over. Do not ever use force on the fish.
Total cooking time will be about 4 mins per side and because we want it well done, use a spatula to lightly press it down. When the fish is bouncy on pressing its done. Total time approx 12 mins.
Drizzle a little olive oil and let it rest for at least 5 mins before slicing.
Lovely keto meal which needs nothing more to be perfect. Except some fresh coriander to counter the heat from the pepper.
