Why it works: Sugar and cream are a kitchen classic. They rank in the top 9% of all ingredient pairs, and cooks put them together in 43,450 recipes. Both carry 2,3-butanedione, which smells butter, sweet. The science ↓
Snow Roll
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.
Prepare the cakes
Preheat the oven to 350°F (175°C).
Beat the sugar and egg yolks together for 15 minutes.
Fold in the ground nuts and then gently add the stiffly beaten egg whites.
Pour the mixture into thin baking tins and bake for about 15 minutes.
Allow the cakes to cool completely.
Fill and roll
Whip the heavy cream until stiff, then sweeten and flavor to taste.
Spread the whipped cream on the cooled cake, roll it up, and cut like a jelly cake.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Ground nuts
- Provide the main body and flavor of the sponge, replacing much of the flour structure.
- Eggs
- Whipped whites and beaten yolks give the cake its light, airy structure and rise.
- Granulated sugar
- Sweetens the cake and helps stabilize the beaten egg mixture.
- Heavy cream
- Whipped into a stiff filling that adds moisture and richness to the rolled cake.
The step that matters
Folding in the egg whites. Stiffly beaten whites hold the batter's air. Folding gently rather than stirring keeps that air in, so the thin cakes stay light and do not collapse.
Swap the nuts
How well each one fits the dish's main ingredients (sugar, egg, cream):
- Almondfits better
- Pistachiofits better
- Chestnutfits about as well
- Nutsthe original
Fit is the average pairing score against sugar, egg, cream. Candidates are from the same food group and used in at least 100 recipes.
