Kevin Aherne from Sage Restaurant dropped by Today with Maura and Dáithí to make his Diamond Steak, Duck Fat Chips & My Million-Dollar Butter. 

This, for me, is a great representation of two great products we have in Ireland: Beef & Potatoes. Knowing where your food comes from is key. I have sourced this meat from my town butcher. He has given me all the information, i.e. where the beef has come from, what type of beef it is and how long it’s been aged for. This cut of meat, also known as a rump steak, is inexpensive. Be aware that the longer it’s cooked the tougher it will get so if you like your meat well done, sirloin may be a better option.

Serves: 

  • 2 x 240g diamond steaks
  • 5 x large rooster potatoes cut 6cm x 2cm
  • 200ml duck fat
  • 2 sprigs rosemary finely chopped

For the butter:

  • 100g melted butter
  • 4 sage leaves finely chopped
  • 4 sprigs theme finely chopped
  • 1 tbsp grated horseradish
  • 4 cloves roasted garlic finely chopped
  • 1 x tsp black pepper
  • 1 x tsp salt

Mix together in a bowl and set aside until later. Do not refrigerate

The Chips:

  1. Melt the duck fat in a pan. In an edged baking tray, lay the chips out with spaces between them. Pour the duck fat on top. Bake in the oven gas mark 6 for 15 minutes then carefully turn the chips and bake for a further 10 minutes. Remove the chips from the oven. Leave to cool slightly then pour the duck fat
  2. out of the tray into a heat proof container. Place the chips back in the oven gas mark 6 for 25 minutes. Remove from the oven season with salt and sprinkle the chopped rosemary on top. They are now ready to serve.

The steak

  1. Always cook your beef at room temperature. In a really hot pan, sear the steak to your liking on each side. Remove from the pan and leave for 4-5 minutes to rest. This will help to keep all the juices in the steak once cut
  2. For serving the dish, simply stack the chips on each other like a tower. Place the steak alongside and spoon two generous tablespoons of My Million Dollar Butter on top.
