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 ↓

Sultana Cake

Ingredients

Directions

Mix the batter

  1. In a bowl, combine 1 cup of flour.

  2. Rub in ¼ cup of butter until the mixture resembles breadcrumbs.

  3. Add ¼ cup of sugar, 1 teaspoon of baking powder, and ¾ cup of sultana raisins.

  4. Grate the zest of the lemon into the bowl.

  5. Chop the candied peel and add it to the mixture.

  6. In a small bowl, mix 2 tablespoons of milk with 2 egg yolks.

  7. Stir the milk and egg mixture into the other ingredients until combined.

Add the whites and bake

  1. Grease a cake tin.

  2. Whip the egg whites until stiff and gently fold them into the batter.

  3. Pour the batter into the prepared tin and bake in a preheated oven at 400°F (200°C) for 1 hour and 15 minutes.

Cool

  1. Once baked, turn the cake out onto its side or a sieve to cool before serving.

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.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

All-purpose flour
Forms the structure that holds the cake together as it bakes.
Butter
Rubbed into the flour to add richness and a tender crumb.
Sugar
Adds sweetness and helps give the cake a tender, browned crust.
Egg yolks
Add richness and help bind the batter together.
Egg whites
Whipped to stiff peaks, they trap air that lightens the cake.
Baking powder
Releases gas in the batter, helping the cake rise in the oven.

The step that matters

Folding in the whipped egg whites. Whites hold air only when whipped to stiff peaks. Stirring vigorously knocks that air out, so the cake rises less and turns denser. Fold gently, just until no white streaks remain.

Swap the lemon

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