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 ↓

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.
Prepare the batter
Beat the egg yolks and whites separately.
Mix the yolks with the sugar and butter until creamy.
Add the sifted flour, cream of tartar, and milk mixed with baking soda.
Fold in the raisins, citron, and lemon peel.
Gently fold in the beaten egg whites.
Bake
Pour the batter into a paper-lined cake tin.
Bake for 1 hour in a moderate oven at 350°F (175°C).

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
- Whipped whites trap air, giving the cake its light, open structure, while yolks add richness.
- All-purpose flour
- Flour builds the cake's structure once its proteins set in the oven.
- Butter
- Creamed butter adds fat that tenderises the crumb and carries flavour.
- White sugar
- Sugar sweetens the cake and, creamed with butter, helps hold air in the batter.
- Cream of tartar
- An acid that stabilises beaten egg whites and helps them hold their volume.
- Baking soda
- Reacts with the acidic cream of tartar and milk to produce gas that helps the cake rise.
The step that matters
Gently fold in the beaten egg whites.. Beaten whites hold the air that makes the cake light. Stirring or mixing vigorously deflates them, so fold them in with a light, sweeping motion until just combined.
