Mrs. J. Hart, High-class cookery made easy (1880)
“ 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. ”
