Directions:
Lamb sweetbreads are not always procurable, but a stroll through the markets occasionally reveals a small lot of them, which can invariably be had at a low price, owing to their excellence being recognized by but few buyers. Wash them well in salted water and parboil fifteen minutes; when cool, trim neatly and put them in a pan with just butter enough to prevent their burning; toss them about until a delicate color; season with salt and pepper and serve, surrounded with tomato sauce.
