Grilled pepper steak with fried garlic potatoes

1.Preheat oven to 200C. For fried garlic potatoes, cook potatoes in a saucepan of boiling salted water until just tender (6-8 minutes), drain well. Heat oil and butter in a large frying pan over medium-high heat, add potatoes and toss occasionally until golden and crisp, adding garlic in the last minute or two of cooking (8-10 minutes). Season to taste and keep warm.

2.Meanwhile, coarsely crush peppercorns and 1 tsp sea salt with a mortar and pestle, then press onto both sides of steak. Heat oil in a large frying pan over medium-high heat, add steaks and cook, turning once, until well-browned and a crust forms (4-5 minutes each side). Transfer to a baking tray and roast until cooked to your liking (4-5 minutes for medium-rare), then set aside to rest.

3.Meanwhile, deglaze pan with red wine, scraping base with a wooden spoon, and boil until almost completely reduced (1-2 minutes). Add stock, boil until a glaze forms, remove from heat and add vinegar to taste. Serve spooned over steak along with fried garlic potatoes and a crisp, green salad.
