Why it works: Syrup and sugar match in chemistry and in kitchens. They rank in the top 6% of all ingredient pairs, and cooks put them together in 5,842 recipes. Both carry ethanol, which smells alcoholic, ethereal. The science ↓
Burnt Filbert Ice Cream
Ingredients
Directions
Prepare the nuts
Roast the Barcelona nuts in the oven until well done.
Pound the roasted nuts slightly and mix with some cream.
Make the custard
In a saucepan, combine the eggs, cream, and syrup; boil until thick.
Strain the thickened mixture through a sieve and freeze.
Burn the sugar and finish
In another saucepan, heat the powdered sugar until it melts and turns a fine brown.
Quickly mix the thickened cream mixture with the burnt sugar, strain again, and freeze.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Thicken the custard base as they set when heated, giving the ice cream body.
- Cream
- Provides richness and fat, giving the ice cream a smooth, creamy texture.
- Barcelona nuts
- Supply the nutty flavour that is the base of the ice cream.
- Powdered sugar
- Caramelises when burnt, adding a deep, bittersweet browned flavour.
- Syrup
- Adds sweetness and helps keep the ice cream soft when frozen.
The step that matters
Heating the powdered sugar to a fine brown. Sugar goes from amber to bitter and burnt within seconds. Removing it from the heat at the right colour gives a pleasant caramel flavour instead of an acrid one.
Swap the nuts
How well each one fits the dish's main ingredients (cream, egg, syrup, sugar):
- Almondfits better
- Chestnutfits better
- Pistachiofits better
- Nutsthe original
Fit is the average pairing score against cream, egg, syrup, sugar. Candidates are from the same food group and used in at least 100 recipes.
