Why it works: Almond and flour are a kitchen classic. They rank in the top 5% of all ingredient pairs, and cooks put them together in 8,673 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Almond Custard
Ingredients
Directions
Make the custard base
Mix the potato flour smoothly with a little milk.
Boil the remaining milk and add the flour mixture.
Stir until thickened, then remove from heat.
Dissolve the gelatine in a little warm water and add to the mixture.
Beat the egg yolks and sugar together, then combine with the milk mixture.
Flavour and set
Add the chopped almonds and almond essence, mixing well.
Pour into a mold and refrigerate until set.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potato flour
- Thickens the milk into a smooth, sliceable custard.
- Egg yolks
- Add richness and help thicken the custard as they heat.
- Gelatine
- Sets the custard so it holds its shape when chilled.
- Milk
- Forms the liquid base that the flour and yolks thicken.
- Sugar
- Adds sweetness and balances the flavour of the almonds.
The step that matters
Stir the flour mixture until thickened. Potato flour needs to be fully cooked in the boiling milk to thicken properly and lose its raw starchy taste. Stopping too early leaves the custard thin, while overheating egg yolks later can curdle them.
Swap the potato
How well each one fits the dish's main ingredients (almond, flour, sugar, egg, milk):
- Arrowrootfits better
- Sweet potatofits better
- Beetrootfits better
- Potatothe original
Fit is the average pairing score against almond, flour, sugar, egg, milk. Candidates are from the same food group and used in at least 100 recipes.
