2 lbs. of spinach, 1 chopped up onion, 1 oz. of butter, 1 pint of milk, the juice of 1 lemon, 1-1/2 oz. of Allinson fine wheatmeal, and pepper and salt to taste. This will make about 3 pints of SOUP. Wash the spinach well, and cook it in 1 pint of water with the onion and seasoning. When the spinach is quite soft, rub all through a sieve. Mix the wheatmeal with the melted butter as in the previous recipe, stir into it the spinach, add the milk; boil all up, and add the lemon juice last of all. If the SOUP is too thick, add a little water.
