Why it works: Cocoa and vanilla work together. They rank in the top 4% of all ingredient pairs, and cooks put them together in 357 recipes. Both carry sotolon, which smells curry, maple. The science ↓
Chocolate Mould
Ingredients
Directions
Make the custard
Smooth the potato flour, wheatmeal, and cocoa with some of the milk.
Add sugar to the remaining milk.
Boil the mixture.
Thicken with the smoothed ingredients.

Vanilla and sugar barely smell alike, yet cooks put them together in 35,032 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 firm, smooth mould that holds its shape when turned out.
- Fine wheatmeal
- Adds body and thickening so the mixture sets rather than staying liquid.
- Cocoa
- Gives the mould its chocolate flavour and colour.
- Milk
- Forms the liquid base that the starches thicken and set.
The step that matters
Thicken with the smoothed ingredients. Starch must be smoothed in cold milk first, then added to boiling milk while stirring, so it disperses evenly without lumps. Simmering then cooks the starch fully, which is what makes the mould set firm when cooled.
Swap the potato
How well each one fits the dish's main ingredients (milk, flour, cocoa, vanilla, sugar):
- Arrowrootfits better
- Capsicumfits about as well
- Potatothe original
- Sweet potatofits about as well
Fit is the average pairing score against milk, flour, cocoa, vanilla, sugar. Candidates are from the same food group and used in at least 100 recipes.
