  • 150g radishes, trimmed
  • 1 tbsp sea salt flakes
  • 100g Essential Unsalted Dairy Butter, softened
  • 1 tbsp lemon thyme, chopped
  • 1 clove/s clove garlic, crushed
  • 3 British thick cut sirloin steaks
  • Vegetable or sunflower oil, for brushing


  1. Grate the radishes, layer them in a colander and sprinkle with the sea salt flakes. Place the colander on a plate and leave to stand for about 30 minutes, until a pool of juice has collected on the plate.

  2. Rinse under plenty of cold running water. Squeeze out any remaining juices with your hands and pat the radishes dry thoroughly in a clean cloth, or with kitchen paper.

  3. Beat the butter in a bowl with the thyme, garlic and grated radish. Check the seasoning, and spoon into a serving dish. Cover and chill until ready to serve.

  4. Brush the steaks with oil and season. Heat a ridged griddle or heavy-based frying pan. When hot, add the steaks and fry until well browned, about 2 minutes on each side for rare, or 3-4 minutes for medium and 5-6 minutes for well done. Serve sliced, topped with spoonfuls of the flavoured butter.

Cook’s tip

To cook on the barbecue: Prepare and light it, then when ready, cook the steaks for 2-3 minutes on each side. The cooking time will vary depending on the heat of the barbecue and the distance from the coals. For medium to well-done steaks, you will need to cook them for longer.
