Why it works: Milk and vanilla are a kitchen classic. They rank in the top 5% of all ingredient pairs, and cooks put them together in 19,187 recipes. Both carry ethyl caproate, which smells fruity, apple peel. The science ↓

Ingredients
Directions
Make the pudding
Smooth the potato flour, whole wheat flour, and cocoa powder with some of the milk.
Add sugar to the remaining milk.
Bring the mixture to a boil.

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, rich custard-like body.
- Whole wheat flour
- Adds further thickening and body to the mixture.
- Cocoa powder
- Provides the chocolate flavor and darkens the mousse.
- Milk
- Forms the liquid base that the flours thicken and sets as it cools.
The step that matters
Smoothing the flours with milk before thickening. Starch lumps form if flour is added directly to boiling liquid. Mixing it into a cool portion of milk first lets the starch disperse evenly, so it thickens smoothly when stirred into the hot mixture.
Swap the potato
How well each one fits the dish's main ingredients (milk, flour, wheat, cocoa powder, vanilla, sugar):
- Arrowrootfits better
- Sweet potatofits better
- Beetrootfits about as well
- Potatothe original
Fit is the average pairing score against milk, flour, wheat, cocoa powder, vanilla, sugar. Candidates are from the same food group and used in at least 100 recipes.
