Why it works: Cinnamon and allspice match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 5,536 recipes. Both carry estragole, which smells anise, licorice. The science ↓

Chocolate Tart

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

Prepare

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

Make the batter

  1. Beat the yolks of the eggs with the sugar until well combined.

  2. Add the grated chocolate, cinnamon, allspice, citron, jelly, vanilla, raisins, and baking powder to the egg mixture.

  3. Gently fold in the beaten egg whites.

  4. Crush the browned Uneeda crackers and mix them into the batter.

Bake

  1. Pour the mixture into a tart pan and bake for 30-35 minutes.

Vanilla and sugar barely smell alike, yet cooks put them together in 35,032 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

Eggs
Whites trapped by folding give the tart lift, while yolks add richness and set the structure.
Chocolate
Adds fat and deep flavor, giving the tart a rich, dense body.
Baking powder
Releases gas in the batter, helping the tart rise and turn lighter in the oven.
Sugar
Sweetens the batter and helps the yolks blend into a smooth base.

The step that matters

Gently fold in the beaten egg whites. Egg whites hold air bubbles that give lift. Stirring vigorously deflates them, so the tart bakes up dense instead of light.

Swap the allspice

How well each one fits the dish's main ingredients (egg, cinnamon, chocolate, vanilla, raisin, sugar):

  1. Nutmegfits better
  2. Cardamomfits better
  3. Clovefits about as well
  4. Allspicethe original

Fit is the average pairing score against egg, cinnamon, chocolate, vanilla, raisin, sugar. Candidates are from the same food group and used in at least 100 recipes.
