Why it works: Flour and raisin match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 9,075 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Luncheon Cake
Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Make the batter
Combine lukewarm water and enough flour in a bowl to create a thick batter. Stir in salt and homemade yeast.
Flour the washed currants and stoned raisins.
Add the floured currants and raisins to the batter when it is light.
Make the dough
Cream together sugar and butter in another bowl.
Add the creamed mixture and 1 pound of flour to the batter.
Mix in enough milk to form a soft dough.
Knead the dough well.
Bake
Place the dough in a pan and let it rise again.
Bake in a moderate oven at 350°F (175°C) until done.

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.

Flour and butter 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
- Yeast
- Ferments and leavens the batter so the cake rises and becomes light.
- Flour
- Provides the structure that holds the batter and dough together as the cake sets.
- Butter
- Adds fat for richness and a tender crumb.
- Sugar
- Adds sweetness and helps browning during baking.
- Dried currants
- Add fruit flavour and chewy texture throughout the cake.
The step that matters
Add the floured currants and raisins when the batter is light. Yeast must first ferment the batter until it is bubbly and light. Adding the fruit too early can weigh down the batter, while flouring the fruit helps keep it spread evenly rather than sinking to the bottom.
Swap the currant

Fit is the average pairing score against flour, raisin, sugar, butter, milk. Candidates are from the same food group and used in at least 100 recipes.
