Name: Mary’s Cream Sponge Cake
Ingredients: 8 egg yolks; 2 cups white sugar; 2 teaspoons baking powder; flour (enough to make a batter); 3 egg whites; 1 pound sugar (for icing); grated coconut (for sprinkling)

Why it works: Sugar and flour are a kitchen classic. They rank in the top 15% of all ingredient pairs, and cooks put them together in 92,116 recipes. Both carry phenylacetaldehyde, which smells hawthorne, honey. The science ↓

Mary’s Cream Sponge 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

Preheat the oven to 350°F (175°C).
Beat the egg yolks until they are light and creamy.
Sift the baking powder with the flour and mix it with the egg yolks and sugar.

Bake the layers

Pour the batter into three greased jelly tins and bake until golden.

Ice and assemble

For the icing, beat the egg whites and gradually add 1 pound of sugar until stiff.
Spread the icing between the baked layers and sprinkle grated coconut on each layer.

Egg and flour barely smell alike, yet cooks put them together in 106,462 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 yolks: Add richness and help build a soft, tender crumb.
Flour: Forms the structure that holds the sponge together as it bakes.
Baking powder: Releases gas in the batter so the layers rise and lighten.
Sugar: Sweetens the cake and helps keep the crumb moist and tender.
Egg whites: Whipped into a foam that gives the icing its light, stiff body.

The step that matters

Beating the egg whites for the icing. Whites must be beaten until stiff while adding sugar gradually. Sugar added too fast or whites over-beaten can make the foam grainy, weepy, or collapse.
