Cauliflower, leek and mustard soup

Main Serves 3 45 min
Creamy vegetarian soup with a warming touch of mustard. The key to a full-bodied flavour is to gently and patiently sweat the alliums before adding the rest of the ingredients. Leave it chunky or blitz into velvety smoothness. Add a pinch of grated Parmesan or Gruyère at the end, or a swirl of cream. This is especially good with a side of garlic bread.

Ingredients

  • 2 leeks, finely sliced
  • 1 celery stick, finely diced
  • knob of butter
  • 1 small cauliflower, broken into florets, stalk chopped.
  • 1 potato, peeled and diced
  • 2 garlic cloves, chopped
  • leaves from 1 sprig of thyme
  • 700ml chicken or veg stock
  • 1 tbsp wholegrain mustard
  • dash cream, optional
  • salt and pepper
