The British term for wrapping meat around a stuffing, browning it and finishing it in a brown sauce is called an “olive,” although there are no olives in it. Perhaps the word referred to the final “olive-like” shape the meat took when it was tied up and cooked. Beef, veal and even fish olives have been part of the British cuisine since the 16th century.
Cut slices of a fat rump of beef six inches long and half an inch thick, beat them well with a pestle, make a forcemeat of bread crumbs, fat bacon chopped, parsley, a little onion, some shred suet, pounded mace, pepper and salt; mix it up with the yelks of eggs, and spread a thin layer over each slice of beef, roll it up tight and secure the rolls with skewers, set them before the fire, and turn them till they are a nice brown, have ready a pint of good gravy thickened with brown flour and a spoonful of butter, a gill of red wine with two spoonsful of mushroom catsup, lay the rolls in it and stew them till tender: garnish with forcemeat balls.
