Required : A pair of sweetbreads. Two mushrooms. A little stock. Half an ounce of butter. Quarter of an ounce of flour. One gill of milk. Salt, pepper, and lemon-juice. The yolk of one egg. (Sufficient for four.)
Cook the mushrooms until tender in a little stock, then cut also into neat dice. Melt the butter in a saucepan, stir in the flour smoothly, then add the milk, and stir it over the fire until it boils. Then add salt, pepper, and lemon-juice to taste. Next, beat up the yolk and add it.
Put in the sweetbreads and mushroom, and let all simmer gently for a few minutes, until the mixture is hot through. Turn it into china or paper ramaquin cases. Sprinkle a little chopped parsley or truffle on each, and serve.
Cost, about 2s. 4d.
