Baking Powder Doughnuts

Ingredients

Directions

The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.

Preheat your oven to 350°F (175°C).
In a large bowl, rub the baking powder into the flour.
Then, rub in the lard, sugar, cinnamon, and a little salt.
Beat the egg well, add part of the milk, and stir into the batter.
Add the remaining milk until the dough reaches a rollable consistency.

Recipe from a historical cookbook (Internet Archive).

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.
