Sweetbreads a la Creme

• 3 Pairs of Sweetbreads
• 10 Mushrooms
• 1½ Tablespoonfuls of Butter

Clean and parboil the Sweetbreads for twenty minutes. Then remove all veins and nerves and chop the meat into pieces of an inch and a half. Chop the mushrooms very fine indeed. Put the butter in a saucepan, and when it melts, add the flour, being careful not to let it brown. When perfectly smooth, add the milk and stir constantly till it boils. Add the chopped mushrooms
