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, wheat flour, and cocoa with some of the milk.
Add sugar to the remaining milk, bring it to a boil, and thicken with the smoothed ingredients.
Let the mixture simmer for 10 minutes, stirring frequently.
Add the vanilla essence and mix well.
Set and serve
Pour the mixture into a wetted mold, let it cool, then turn out and serve plain or with cold white sauce.

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, firm pudding as its starch swells when heated.
- Wheat flour
- Adds body and helps the pudding hold its shape once cooled.
- Cocoa powder
- Provides the chocolate flavour and colour of the pudding.
- Milk
- Forms the liquid base that the starches thicken into a custard-like set.
The step that matters
Smoothing the flours with milk before adding. Starch lumps form if dry flours go straight into hot liquid, because the outer grains swell and seal off the inside. Mixing them into cold milk first lets the starch disperse evenly so it thickens smoothly.
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.
