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 ↓

Hash 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. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.

Make the cake

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

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

  3. Add the egg whites and mix well.

  4. Stir in the milk, baking soda, cream of tartar, and flour until combined.

  5. Pour the batter into a greased cake pan and bake for 25-30 minutes.

Make the frosting and finish

  1. For the frosting, combine the chopped raisins, hickory nuts, sugar, and water in a saucepan.

  2. Boil the mixture until it reaches a stringing consistency.

  3. Spread the frosting over the cooled cake.

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.

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, giving the cake a tender, rich crumb.
Egg whites
Provide structure and lift as they set in the oven.
Flour
Forms the main structure of the cake as the batter sets.
Baking soda
Reacts with the acid in the batter to help the cake rise.
Cream of tartar
Acidifies the batter and stabilizes the egg whites for a lighter texture.
Sugar
Sweetens the cake and helps create a soft, tender texture when creamed.

The step that matters

Boil the frosting to a stringing consistency. Sugar syrup must reach the right concentration: too little boiling leaves a runny frosting that will not hold, while overboiling makes it hard and grainy as it cools.

Swap the raisin

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

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

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