Ingredients
Directions
The book says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Melt the lard in the milk.
Combine the yeast, sugar, and melted lard with the milk to make a stiff batter.
Let the batter rise until doubled in size.
Mix and knead the dough roughly, then let it rise again.
Roll out the dough to 1 inch thick and cut with a large biscuit cutter.
Spread melted butter on each piece, fold them together, and let them rise until very light.
Bake in a 400°F (200°C) oven until golden brown and serve hot.
Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.
