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

  1. Preheat the oven to 350°F (175°C).

Make the batter

  1. Rub together the flour and baking powder with the butter and sugar.

  2. Add the milk and mix well.

  3. Beat the eggs until light and add them along with the almond essence. Mix all ingredients together.

Bake

  1. Pour the mixture into a well-buttered cake tin.

  2. Bake for two hours.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Flour
Forms the main structure of the cake as its starch sets during baking.
Eggs
Add structure and richness, and when beaten light they help the cake rise and turn tender.
Baking powder
Releases gas in the batter so the cake rises and becomes light.
Butter
Adds fat for a tender crumb and rich flavour.
Brown sugar
Sweetens the cake and adds moisture and a deeper, caramel-like flavour.
Milk
Adds moisture and loosens the batter so it mixes and bakes evenly.

The step that matters

Beat the eggs until light. Beaten eggs trap air that helps the cake rise before the structure sets, so under-beaten eggs can give a denser cake.

Swap the currant

How well each one fits the dish's main ingredients (flour, butter, raisin, almond, sugar, egg, milk):

  1. Vanillafits better
  2. Figfits better
  3. Coconutfits better
  4. Currantthe original

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