Russian Sauce
Place a stew-pan on the fire, slice three onions, let them brown in one ounce of butter, a pinch of pepper and salt; cover with a tight cover till the onions are dissolved; add one ounce of flour, a cup of stock, a glass of cream; stir over the fire for five minutes; pass through a pointed strainer; keep hot in the banbery.
What is meant by a banbery for keeping sauces a young cook may not know. I will explain. Procure a square-topped pan almost like a roasting-pan, and fill it half-full of boiling water. Set the little pans into it, to keep sauces hot when made, and to prevent them burning. Set the sauces in with small bits of butter on the top, so as not to let a skin form.
