Rare roast beef with horseradish dressing

Method

• step 1

  Whisk the creme fraiche, horseradish, honey and chives and add enough water to make a drizzleable dressing. Season well and chill while you make the beef. Put the onions in a bowl and add a little splash of vinegar and water. Toss and leave to sit.

• step 2

  Heat the oven to fan 180C. Oil the beef all over and season really well. Heat a non-stick frying pan to very hot and add the beef. Sear all over, turning until a good colour on all sides.

• step 3

  Transfer to a small roasting tin and roast for 10 minutes or until medium rare. Remove and cover with foil and leave to cool to room temperature.

• step 4

  To assemble, tear the lettuce and wash and dry the leaves. Put on a platter. Slice the beef thinly as possible and drape all over the lettuce. Scatter the onions and then drizzle with the dressing. Finish with more chives.
