Why it works: Butter and flour are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 124,287 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓

Ingredients
Directions
The book says “a quick oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Make the batter
Cream together the brown sugar and butter.
Add the beaten eggs, currants, and ammonia.
Gradually mix in the flour until combined.
Bake
Drop spoonfuls of the mixture onto baking pans sized like walnuts.
Bake in a moderate oven at 350°F (175°C) until golden.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

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
- Eggs
- Bind the batter and add structure and moisture to the cakes.
- Butter
- Adds richness and fat, giving the cakes tenderness and flavor.
- Brown sugar
- Adds sweetness and moisture, and helps the cakes brown.
- Flour
- Provides the main structure that holds the cakes together as they bake.
- Ammonia
- Acts as a leavening agent, helping the cakes rise and spread lightly.
The step that matters
Gradually mix in the flour until combined. Adding flour gradually and mixing only until combined keeps the batter from overdeveloping gluten, which would make the cakes tough.
Swap the currant
How well each one fits the dish's main ingredients (sugar, butter, flour, egg):
- Raisinfits better
- Vanillafits better
- Figfits better
- Currantthe original
Fit is the average pairing score against sugar, butter, flour, egg. Candidates are from the same food group and used in at least 100 recipes.
