Why it works: Lemon and ginger match in chemistry and in kitchens. They rank in the top 5% of all ingredient pairs, and cooks put them together in 5,154 recipes. Both carry beta-phellandrene, which smells minty, terpene. The science ↓

To Make Gingerbread

Oven, in the book's wordsA gentle oven

Ingredients

Directions

The book says “a gentle oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.

Prepare

Preheat your oven to 300°F (150°C).

Make the dough

In a large bowl, combine the flour, lemon peel, treacle, ginger, caraway seeds, butter, and sugar, and mix until well combined and a dough forms.
Shape the dough into small buttons or cakes.

Bake

Place on a baking sheet and bake in the preheated oven until firm.

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 main structure that holds the dough together as it bakes.
Treacle (or molasses): Adds moisture, dark colour and a deep sweetness to the gingerbread.
Ground ginger: Supplies the warm, spicy flavour that defines the gingerbread.
Butter: Adds fat for tenderness and richness in the baked dough.
Sugar: Adds sweetness and helps the cakes brown as they bake.
