Why it works: Cinnamon and almond match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 3,514 recipes. Both carry eucalyptol, which smells eucalyptus, herbal. 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. 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.

Prepare the batter

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

  2. In a bowl, mix the egg yolks, cinnamon, grated potatoes, chopped citron, rye bread crumbs, chopped almonds, brandy, baking powder, and sugar until well combined.

  3. In a separate bowl, beat the egg whites until stiff peaks form.

  4. Gently fold the egg whites into the potato mixture.

Bake and assemble

  1. Divide the batter into three layers and bake for 25-30 minutes or until golden.

  2. Once cooled, spread whipped cream between the layers.

Cinnamon and sugar barely smell alike, yet cooks put them together in 30,779 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

Egg whites
Whipped into stiff peaks, they trap air that lifts and lightens the batter.
Egg yolks
Add richness and help bind the batter as it sets in the oven.
Rye bread crumbs
Add body and absorb moisture, giving the cake a dense, crumbly texture.
Grated potatoes
Add moisture and body to the batter, keeping the cake tender.
Sugar
Adds sweetness and helps the cake brown as it bakes.

The step that matters

Folding the egg whites into the potato mixture. Folding gently keeps the air trapped in the whipped whites. Stirring or deflating them makes the layers dense and flat instead of light.

Swap the potato

How well each one fits the dish's main ingredients (egg, cinnamon, rye, bread, almond, brandy, sugar):

  1. Arrowrootfits better
  2. Sweet potatofits better
  3. Beetrootfits better
  4. Potatothe original

Fit is the average pairing score against egg, cinnamon, rye, bread, almond, brandy, sugar. Candidates are from the same food group and used in at least 100 recipes.
