Why it works: Milk and potato are a kitchen classic. They rank in the top 9% of all ingredient pairs, and cooks put them together in 3,611 recipes. Both carry (e,z)-2,6-nonadienal, which smells cucumber, melon. The science ↓
Arrow-root Pudding
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Make the custard
Wet the arrow-root with cold milk in a bowl.
Pour boiling milk over the mixture, stirring briskly until combined.
Add the powdered sugar and mix well.
Incorporate the eggs and your choice of lemon juice, grated rind, or mace.
Bake and serve
Line a dish with thin potato paste.
Bake the mixture by itself.
Bake at 350°F (175°C) until set.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Arrow-root
- Thickens the milk into a smooth, set custard as it cooks.
- Eggs
- Set the pudding into a firm, sliceable structure as they cook.
- Powdered white sugar
- Adds sweetness and softens the set texture of the pudding.
The step that matters
Stirring the boiling milk into the arrow-root. Starch must be wetted with cold milk first, then hit with boiling milk while stirring briskly. This swells the starch evenly and prevents lumps, so the custard thickens smoothly instead of clumping.
Swap the potato
The recipe marks potato as optional. How well each one fits the dish's main ingredients (milk, sugar, egg, lemon):
- Asparagusfits better
- Arrowrootfits better
- Sweet potatofits better
- Potatothe original
Fit is the average pairing score against milk, sugar, egg, lemon. Candidates are from the same food group and used in at least 100 recipes.
