Lightly rinse the yellowtail fillets with water and pat them dry with paper towels. Sprinkle with salt and black pepper.

In a container, mix the ingredients marked with ☆ along with the grated garlic to make the marinade.

Coat the fillets from step 1 with the marinade from step 2. If you have time, let them soak for about 30 minutes.

Lightly pat dry and coat with all-purpose flour. Melt the butter in a frying pan. (Do not discard the leftover marinade)

Start sautéing on low heat. Once one side is cooked, flip and add the remaining marinade. Once the marinade is heated through, it's ready to serve.
