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
Mix the potato flour smoothly with a little milk.
Boil the remaining milk and pour it over the potato flour, stirring continuously.
Return the mixture to the stove and simmer gently for 3 minutes.
Add the sugar and egg yolks, stirring until the mixture thickens.
Dissolve the gelatine in a little hot water and add it to the custard, then strain.
Finish
Stir in the chopped almonds and add almond essence to taste.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Flour and milk barely smell alike, yet cooks put them together in 78,219 recipes: they work on texture and structure more than aroma.
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, set custard without lumps.
- Egg yolks
- Enrich the custard and help it thicken as it heats.
- Gelatine
- Sets the custard so it holds its shape when cooled.
- Milk
- Forms the liquid base that the thickeners set into custard.
- Sugar
- Sweetens the custard and balances its richness.
The step that matters
Adding the egg yolks. Egg yolks can scramble if the custard is too hot or stirred too little. Adding them to a thickened, gently heated mixture while stirring keeps them smooth and lets the custard thicken evenly.
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.
