Why it works: Sugar and vanilla are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 35,032 recipes. Both carry beta-damascenone, which smells apple, rose. The science ↓
Walnut Creams
Ingredients
Directions
Make the paste
In a bowl, combine the egg white and water.
Gradually stir in enough icing sugar to form a very stiff paste.
Add a few drops of vanilla for flavor.
Shape and finish
Mould the mixture into round balls the size of small marbles.
Split the walnut kernels in half and press one half onto each side of the balls.
Leave the walnut creams in a cool place for several hours to harden.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Icing sugar
- Sweetens the paste and, with the egg white, gives it a stiff, sliceable body that sets.
- Egg white
- Binds the icing sugar into a stiff paste that holds its shape as it firms.
- Shelled walnuts
- Add crunch and a nutty flavor that contrasts with the sweet, soft centre.
The step that matters
Gradually stir in the icing sugar. Adding the sugar slowly lets the egg white absorb it evenly. Too much at once leaves dry lumps, while too little leaves a paste too soft to hold its shape and harden.
Swap the walnut
How well each one fits the dish's main ingredients (egg, sugar, vanilla):
- Almondfits better
- Chestnutfits better
- Hazelnutfits better
- Walnutthe original
Fit is the average pairing score against egg, sugar, vanilla. Candidates are from the same food group and used in at least 100 recipes.
