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 ↓
Mocha Torte
Ingredients
Directions
The book says “a moderate oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Make the batter
Beat the yolks of the eggs with the powdered sugar until well combined.
Add the mocha essence, flour, and baking powder, mixing until smooth.
Gently fold in the stiffly beaten egg whites.
Pour the batter into a greased cake pan or two‑layer cake tins.
Bake and fill
Bake at 400 °F (200 °C) until a toothpick comes out clean.
For the filling, mix the whipped cream with mocha essence and sweeten with powdered sugar.
Spread the cream between the layers and on top of the torte.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Whipped whites give the torte its light, airy structure as they set in the oven.
- All-purpose flour
- Starch and gluten form the cake's set crumb once heated.
- Baking powder
- Releases gas when heated, helping the batter rise and lighten.
- Heavy cream
- Whipped into a filling that adds richness and moisture between the layers.
- Powdered sugar
- Sweetens the batter and cream and helps give a tender crumb.
The step that matters
Folding in the egg whites. Whites hold air only when whipped stiff, and overmixing or stirring vigorously deflates them. Folding gently keeps the batter light so the torte rises evenly and stays airy.
