Name: Little Hard Gingerbread
Ingredients: 1 quart molasses; 1 pound sugar; 1 pound butter; 1 tablespoon baking soda, dissolved in ½ cup milk; 2 tablespoons ginger; flour, as needed

Why it works: Butter and milk are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓

Little Hard Gingerbread

Oven, in the book's wordsA quick oven

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.

Prepare the dough

Warm the butter and molasses together.
Mix all ingredients in a bowl, adding flour until the mixture is stiff.
Knead the dough until your elbows ache.

Shape and bake

Roll the dough to a thickness of ¼ inch.
Cut into oblong cakes using a jagging iron.
Bake in a 400°F (200°C) oven, watching carefully to prevent burning.

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.

Butter and flour barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.

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

What each ingredient does

Molasses: Adds sweetness, dark colour and moisture to the dough.
Sugar: Adds sweetness and helps the cakes brown in the oven.
Butter: Adds fat, which gives richness and tenderness to the dough.
Baking soda: Reacts with the acidic molasses to lighten the dough and aid browning.
Ginger: Adds the warm, spicy aroma that defines the cake.
Flour: Provides structure, so the dough becomes stiff enough to knead and cut.

The step that matters

Bake in a 400°F (200°C) oven, watching carefully to prevent burning.. Sugar and molasses darken quickly at high heat, so the cakes can scorch before they are fully baked through. Checking them closely keeps them evenly browned and prevents a bitter taste.
