Directions :

• Preheat the oven to 200°C (400°F).
• Place the fish fillet on a work surface and pat it dry using paper towel.
• Dip fish in the flour and shake to remove any excess.
• Season to taste with salt and pepper.
• Heat a skillet over medium-high heat and add equal quantities of butter and oil. When the butter begins to foam, sear the fish on both sides so it's nicely coloured.
• Finish cooking the fish in the oven for 10 minutes per each 2 cm (1 in.) of thickness. (Place the fish on a baking sheet or leave it in the skillet if it's ovenproof.)
