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 says “a good sharp oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the batter
Sift the cream of tartar, baking soda, and flour into a large bowl.
Rub in the lard and margarine until well combined.
Add the moist sugar, currants, spice, and eggs.
Mix into a smooth batter using buttermilk as needed.
Bake
Pour the batter into well-papered square bread tins.
Sprinkle a little moist sugar over the top of each cake.
Bake in a preheated oven at 350°F (175°C) until done.

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 cake together as it bakes.
- Eggs
- Bind the batter and add structure and richness as they set in the oven.
- Lard
- Adds fat that tenderises the crumb and keeps the cake moist.
- Cream of tartar
- Acts with baking soda to produce carbon dioxide, helping the cake rise.
- Baking soda
- Reacts with the acid in the cream of tartar to leaven the batter.
- Currants
- Add fruit pieces and a chewy texture throughout the cake.
