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 ↓

A Plain Luncheon Cake

Oven, in the book's wordsA moderate oven

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. Grease a cake tin or two small ones.

  2. Mix the baking powder into the flour.

  3. Rub the butter into the flour until it resembles fine crumbs.

Make the dough

  1. Beat the eggs and add 1-2 tablespoons of cold milk.

  2. Mix the sultanas, candied peel, and sugar into the flour.

  3. Add the eggs and milk, mixing until a stiff dough forms.

Bake and rest

  1. Place the dough into the tin and quickly put it in a 350°F (175°C) oven.

  2. Bake for 1 hour and 15 minutes.

  3. Let the cake cool and do not cut it until the next day.

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 cake as the starch sets during baking.
Butter
Rubbed into the flour to tenderise the crumb and add richness.
Eggs
Bind the dough and add structure and moisture to the cake.
Baking powder
Releases gas in the dough so the cake rises in the oven.
Castor sugar
Adds sweetness and helps tenderise the crumb.

The step that matters

Quickly putting the dough in the oven. Baking powder starts releasing gas as soon as it is moist and warm, so delaying the bake can weaken the rise and leave a denser cake.

Swap the raisin

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

  1. Vanillafits about as well
  2. Raisinthe original
  3. Figfits less well
  4. Coconutfits less well

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