Choose ten or a dozen large tomatoes, cut a slice
from the stem end of each and scoop out the inside. Put the pulp into a
basin with two ounces of melted butter, two tablespoonfuls of lemon
juice, half a pound of chestnuts, boiled and grated, and seasoning of
salt and white pepper to taste. Fill the tomatoes with this, which
should be about the consistency of thick cream, spread with a thick
mayonnaise, garnish with chopped parsley and serve on lettuce leaves.
