Antique English Ironstone Blanc-Mange Mold with the recipe printed on the front for this sweet dessert. Commonly made with milk, sugar and gelatin, or in this case cornstarch, and sweetened with almonds and jelly, it was a very beloved dessert in the 1800's.
John Polson was a famous cornflour manufacturer, he discovered how to make maize into an edible starch, and patented cornstarch in 1854. This mold is from a kitchen where it was used, and has patina and wear that a useful kitchen antique should have. A great addition to your display of white Shelley and other ironstone molds.
