Lettuce Soup

Serves: 2-4

Ingredients:
1 x large lettuce (about  ¾ lb).  [It is ok to use lettuces that have 'bolted'.]
1 medium onion
1 oz butter
2 level tablespoons flour
 ¾ pint hot vegetable stock
 ¾ pint milk
Salt and pepper

METHOD:

Slice the onion and sweat it in the butter for a few minutes over a medium/low heat.
Coarsely shred the lettuce leaves, add to the pan, cover and continue to cook for another 5 minutes or so.
Stir in the flour well, and then pour on the hot stock and milk.
Continue to stir while the soup comes to the boil.  Season, cover and simmer for about 20 minutes.
Using a blender whizz to a smooth consistency, or pass through a sieve.
To serve immediately, return the soup to the pan and bring back to the boil.  Test for seasoning and serve.  A swirl of cream on the top is a nice retro touch!

To freeze, allow to cool and freeze in lidded plastic containers.
