Searing tuna
Heat a stainless steel pan over high heat.
Add 1 tablespoon of ghee.
Season the tuna with salt on both sides and sear the steak briefly but vigorously: top, bottom and sides.
Add another spoonful of ghee and baste the tuna as you would a steak.
Then remove the tuna from the pan and set aside.
Making sauce
Pour off any excess fat from the pan.
Add the green pepper and deglaze with cognac.
Flambé carefully (turn off the extractor hood, move the pan slightly away from the heat).
Thicken cream sauce
Add the cream and brown stock and let it reduce to a lightly thickened sauce.
Taste and season with some extra salt if necessary.
Serve
Serve the tuna steak sliced with the green pepper cream sauce over or on the side.
Finish with fries and a fresh green salad with a spoonful of mayonnaise mixed in.
Tips
- Make sure your pan is piping hot before you put the tuna in, this will help you get a nice crust.
- The tuna should still be pink inside, so don't cook it for too long, otherwise it will become dry.
- If cognac is too strong for you, you can also use a dash of white wine or sherry.
- Not a fan of green pepper? You can also use concave black peppercorns.
- Don't have brown stock? You can also use a dash of veal or chicken stock, which you've reduced first.
