Why it works: Hazelnut and vanilla match in chemistry and in kitchens. They rank in the top 4% of all ingredient pairs, and cooks put them together in 279 recipes. Both carry coumarin, which smells sweet, hay. The science ↓
Hazel Nut Torte
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
In a bowl, stir the egg yolks until light.
Add powdered sugar, grated hazelnuts, and baking powder; mix well.
Beat the egg whites until frothy and fold into the batter.
Bake and make the cream
Bake the mixture in layers at 350°F (175°C).
For the cream, whip the heavy cream until stiff.
Melt the sweet chocolate and mix with whipped cream and vanilla.

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 fat, helping the batter set softly and taste rich.
- Egg whites
- Whipped into foam, they lighten the batter and give the layers lift as they bake.
- Baking powder
- Releases gas when heated, helping the layers rise and become light.
- Grated hazelnuts
- Add nutty flavor and body, with fat that keeps the layers tender.
- Heavy cream
- Whipped to stiff foam, it gives the filling a light, moist, creamy texture.
- Sweet chocolate
- Melted and folded into the cream, it adds sweetness, flavor and a set, rich filling.
The step that matters
Folding in the egg whites. Whites must be beaten until frothy, then folded gently. Stirring or deflating them removes the trapped air that makes the layers rise, so the torte bakes up dense.

- Macadamia nutfits about as well
Fit is the average pairing score against egg, sugar, cream, chocolate, vanilla. Candidates are from the same food group and used in at least 100 recipes.
