Good Plain Gingerbread

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.

Prepare

Preheat the oven to 350°F (175°C).

Make and shape the dough

In a bowl, mix flour, butter, sugar, treacle, cream, and ginger until a stiff paste forms.
Roll out the dough thinly on a floured surface.
Cut into small cakes.
If desired, add candied orange and lemon peel for extra flavor.

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

What each ingredient does

All-purpose flour: Provides the structure that holds the stiff dough together.
Butter: Adds fat for tenderness and a rich texture in the baked cakes.
Sugar: Adds sweetness and helps the cakes brown in the oven.
Treacle: Contributes sweetness, deep color, and the characteristic gingerbread flavor and moisture.
