Here we have the oddly named cousin of the popover, from The Horsford 1886 Almanac and Cook Book. Horsford’s was a brand of baking powder made by the Rumford Chemical Works, which fine company we met briefly on Pi Day. They also made Bread Preparation, Cream Tartar Substitute, Yeast Powder, Acid Phosphate(for drinks), Sulphite (“for preserving cakes”) and Anti-Chlorine (“for paper makers”). I guess if you got tired of preparing bread and drinking phosphates, you could make a little paper. Makes a nice change of pace!
Mix two heaping cups sifted four with one heaping teasponnful Horsford’s Baking Powder; then add two eggs, one large spoonful sugar, a piece of butter as large as a walnut, two cups sweet milk, a little nutmeg and salt; melt the butter. Bake in cups in a quick oven.
The picture above says, “A significant characteristic of Horsford’s Baking powder is its invigorating quality.”
Especially, I would think, Whopovers – which are clearly served to (or rather aimed at) people through some sort of small cannon.
