Ox Palate is the roof of a cow's mouth.
The back third of it is covered with smooth skin, the front two-thirds of it with ridged skin.
Its use in cooking was popular in English country cooking, in classical French cooking and in the genteel cooking of 1800s in America and England.
Larousse cites a 1769 French recipe for "Allumettes de Palais de Boeuf", thin strips of palate which are battered then fried.
The French classify this as a "red offal" (abats rouges.)
Hannah Glasse, in her 1747 book "The art of cookery made plain and easy", gives the following recipes: To stew ox palates, to ragoo ox palates, to fricassée ox palates, to roast ox palates, to pickle ox palates.
Literature & Lore
Blanch for ten minutes an ox palate, drain it, remove the fat, and scrape it carefully; divide it into two parts, and put the palate into a small stewpan with a pint of stock, half an ounce of butter, a little pepper and salt, a bouquet garni, a small onion, and a small carrot. Let the contents simmer for three hours; remove the palate to a cloth, then clean way any fat, and dish with sharp sauce. -- Buckmaster, John Charles. Buckmaster's Cookery. London: George Routledge and Sons. 1874. Page 222.
