Why it works: Flour and buttermilk are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 3,721 recipes. Both carry ethanol, which smells alcoholic, ethereal. The science ↓

Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare the batter
Sift baking soda and cream of tartar with flour.
Rub lard into the flour and make a well in the center.
Add sugar, currants, and a few drops of lemon essence.
Pour in enough buttermilk to create a soft batter.
Bake and serve
Grease sponge cake molds and fill them three-quarters full with batter.
Brush the tops with egg and dust with castor sugar.
Bake in a preheated oven at 400°F (200°C) until golden.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Forms the structure of the cakes as the batter sets in the oven.
- Baking soda
- Reacts with the acid in the cream of tartar and buttermilk to produce gas that lifts the cakes.
- Cream of tartar
- Provides acid that reacts with the baking soda so the cakes rise.
- Lard
- Adds fat that tenderises the crumb and keeps the cakes short.
- Buttermilk
- Moistens the flour and adds acidity that activates the baking soda.
- Currants
- Add sweetness, chewy bursts of fruit, and moisture to the cakes.
The step that matters
Pour in the buttermilk gradually to a soft batter. Too much liquid makes the batter slack and the cakes spread or bake heavy, while too little leaves dry pockets of flour. Mix only until combined, since overworking develops gluten and toughens the crumb.
Swap the currant
How well each one fits the dish's main ingredients (flour, cream, sugar, buttermilk, lemon, egg):

Fit is the average pairing score against flour, cream, sugar, buttermilk, lemon, egg. Candidates are from the same food group and used in at least 100 recipes.
