21. Tomato Puree.
Cut up an onion into rings, chop two beads of garlic, and fry a pale brown in two ounces of butter. Add twenty-four cloves, and two pounds of tomatoes cut up in quarters. Let it simmer gently till the tomatoes are quite soft; strain through a sieve. Add one pint of water, pepper and salt to taste; let it boil up, and put in a tablespoon of butter rolled in as much flour as it will take up; stir well. A few drops of tarragon vinegar are a great improvement.
