Ginger Cakes

Oven, in the book's wordsA warm oven

Ingredients

Directions

The book says “a warm oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.

Prepare the dough

Preheat the oven to 400°F (200°C).
Rub the butter into the flour until well combined.
Mix in the egg, powdered sugar, and ground ginger to form a paste.
Roll out the paste to ¼ inch thick.

Shape and bake

Cut into round cakes, about 2 to 3 inches across.
Bake on iron plates in the preheated oven until golden.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Butter: Rubbed into the flour, it coats the flour and gives the cakes a tender, crumbly texture.
Flour: Forms the main structure of the dough once it is combined with the butter and egg.
Egg: Binds the mixture together so it can form a paste that holds its shape.
Ground ginger: Supplies the spicy aroma and flavor that defines these cakes.
