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 ↓

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. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare
Preheat your oven to 350°F (175°C).
Make the dough
In a bowl, cream together the brown sugar and butter.
Beat in the eggs one at a time.
Stir in the currants and sweet spice.
Dissolve the baking soda in a little milk and add it to the mixture.
Add enough flour to form a dough that can be rolled out.
Shape and bake
Roll out the dough and cut into desired shapes.
Place on a baking sheet and bake for 10-12 minutes or until golden.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Brown sugar
- Adds sweetness and moisture, and helps the cookies brown as they bake.
- Butter
- Provides fat for tenderness and creaming with sugar to build structure.
- Eggs
- Bind the dough and add structure and richness.
- Baking soda
- Reacts with acidity in the dough to produce gas, helping the cookies rise and brown.
- Currants
- Add chewy texture and concentrated sweetness.
- Sweet spice
- Adds aroma and warm flavor throughout the dough.
The step that matters
Dissolving the baking soda in milk. Baking soda must be fully dissolved so it distributes evenly; clumps can leave bitter spots and uneven rising. It needs an acid in the dough to work well, so it should be mixed in before the flour.
Swap the currant
How well each one fits the dish's main ingredients (sugar, butter, egg, milk, flour):

- Figfits better
- Currantthe original
Fit is the average pairing score against sugar, butter, egg, milk, flour. Candidates are from the same food group and used in at least 100 recipes.
