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 ↓
Hazelnut Crunch Ice Cream
Ingredients
Directions
Make the custard
Combine egg yolks, sugar, salt, and liqueur in a 3‑quart pan.
When sugar is dissolved, add milk.
Cook in a double boiler over medium heat until custard is thick enough to coat a spoon, stirring occasionally.
Remove from heat and cool to room temperature; add cream and vanilla.
Chill thoroughly.
Freeze and add crunch
Pour mixture into an ice‑cream freezer and freeze for 10 minutes or until mixture is very stiff.
Add Oregon hazelnut crunch and process an additional 10 minutes or until desired consistency.
Nutrition, whole recipe (rough)

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Thicken the custard as they cook and add richness and a smooth texture.
- Sugar
- Sweetens the base and lowers the freezing point, keeping the ice cream softer.
- Heavy cream
- Adds fat for a creamy, smooth texture that resists iciness.
- Milk
- Adds liquid to the custard base, diluting richness while keeping it creamy.
- Hazelnut liqueur or extract
- Adds hazelnut aroma and flavor to the custard base.
The step that matters
Cooking the custard. Egg yolks thicken as they heat, but overheating can scramble them into lumps. Cook gently over a double boiler, stirring, and stop when it coats a spoon so the base stays smooth.
Swap the hazelnut
How well each one fits the dish's main ingredients (egg, sugar, milk, cream, vanilla):
- Almondfits better
- Chestnutfits about as well
- Hazelnutthe original
- Cocoafits about as well
Fit is the average pairing score against egg, sugar, milk, cream, vanilla. Candidates are from the same food group and used in at least 100 recipes.
