Asparagus spears with wholegrain mustard hollandaise

  • Preparation time: 15 minutes
  • Cooking time: 5 minutes
  • Total time: 20 minutes

Serves: 4 as a starter

Ingredients

2 egg yolks
3 tsp lemon juice
50g salted butter
2 tsp wholegrain mustard
400g bunch asparagus, trimmed

Method

1. Put the yolks and 2 tsp lemon juice in a small blender or food processor; whizz for 30 seconds. Melt the butter in a small pan then, with the blender running, trickle it in.

2. Warm a bowl by pouring a little just-boiled water into it, then empty and dry. Scrape the hollandaise into the bowl and stir in the mustard; season with salt, pepper and more lemon juice to taste. Leave in a warm (not hot) place for up to 30 minutes.

3. Lay the asparagus out in a single layer in a large frying pan. Half-cover with just-boiled water, add a pinch of salt and place over a high heat. Simmer briskly, turning the spears occasionally, until the water has evaporated and the asparagus is tender. Serve with the warm sauce and lemon wedges, if liked.
