Why it works: Sugar and chocolate are a kitchen classic. They rank in the top 13% of all ingredient pairs, and cooks put them together in 15,404 recipes. Both carry guaiacol, which smells smoky, sweet. The science ↓
Passover Chocolate Sponge Cake
Ingredients
Directions
Prepare the batter
Preheat oven to 350°F.
Beat egg yolks and sugar until light and fluffy (about 7 minutes).
Add cold water, orange juice, orange rind, chocolate and cake flour.
Gently fold in stiffly beaten egg whites.
Pour into a 10-inch tube pan with removable insert.
Bake and cool
Bake for 55 to 65 minutes or until cake springs back when gently pressed.
Cool completely, inverted on cake rack, before removing from pan.
Nutrition, whole recipe (rough)
Counts 5 of 6 ingredients. The other 1 aren't in our nutrition table and add nothing above, so the real totals are higher.
What these numbers assume: 5 portions
| Ingredient | Portion assumed | kcal |

| Chocolate | 1 oz (28g) semisweet | 155 |
| Egg | 1 large egg (50g) | 78 |
| Orange | 1 medium (131g) | 62 |
| Sugar | 1 tbsp (12.5g) granulated | 49 |

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Whites beaten stiff and folded in provide the airy lift that gives the sponge its structure.
- Sugar
- Beaten with the yolks to create a light, fluffy base and add sweetness.
- Sweet chocolate
- Adds flavor and richness, and its fat and cocoa solids help give the cake a tender crumb.
- Matzo cake flour
- Provides the light starch structure that holds the sponge together while it bakes.
The step that matters
Folding in the egg whites. Stiffly beaten whites trap air that makes the sponge rise. Folding gently keeps that air in; stirring or deflating the batter leads to a dense, flat cake.
Swap the orange
How well each one fits the dish's main ingredients (egg, sugar, chocolate, flour):
- Vanillafits better
- Raisinfits better
- Datesfits better
- Orangethe original
Fit is the average pairing score against egg, sugar, chocolate, flour. Candidates are from the same food group and used in at least 100 recipes.
