Why it works: Raisin and flour 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 ↓

Potato Cake

Ingredients

Directions

The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.

Make the batter

  1. Cream the butter and sugar together until light and fluffy.

  2. Add the warm mashed potatoes and mix well.

  3. Incorporate the beaten eggs, milk or cream, raisins, and nuts.

  4. Sift together the flour, baking powder, chocolate, cinnamon, cloves, and nutmeg.

  5. Gradually add the dry ingredients to the wet mixture, stirring until combined.

Bake

  1. Pour the batter into a loaf pan and bake at 350°F (175°C) until a toothpick comes out clean.

Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

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

Butter
Creams with sugar to trap air and add richness and tenderness to the crumb.
Sugar
Sweetens the cake and helps create a light, fluffy texture when creamed with butter.
Mashed potatoes
Adds moisture so the cake stays soft and moist.
Eggs
Bind the batter and provide structure and lift as the cake bakes.
Flour
Forms the structure of the cake as its proteins set during baking.
Baking powder
Releases gas during baking so the cake rises.

The step that matters

Gradually add the dry ingredients to the wet mixture. Adding flour in portions and stirring only until combined limits gluten development, keeping the cake tender rather than tough and dense.

Swap the nuts

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

  1. Almondfits better
  2. Chestnutfits better
  3. Pistachiofits about as well
  4. Nutsthe original

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