Why it works: Rice and potato match in chemistry and in kitchens. They rank in the top 7% of all ingredient pairs, and cooks put them together in 851 recipes. Both carry 2-acetyl-1-pyrroline, which smells popcorn, roasted. The science ↓
Rice and Potato Pudding
Ingredients
Directions
The book says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Make the rice base
Prepare the rice as in Baked Rice Pudding.
In a stewpan, combine the rice, milk, sugar, and salt; boil for one hour, adding water if too dry.
Add the potatoes and suet
Boil the potatoes, peel, and mash them; add to the rice mixture.
Chop the suet and mix it into the whole mixture.
Bake
Butter a baking dish, pour the mixture in, and bake at 400°F (200°C) for thirty minutes.

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.

Milk and sugar barely smell alike, yet cooks put them together in 77,875 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
- Rice
- Forms the bulk of the pudding and thickens as it cooks in the milk.
- Milk
- Provides liquid that the rice absorbs, giving a soft, creamy body.
- Potatoes
- Mashed starch that adds body and a dense, smooth texture to the pudding.
- Sugar
- Adds sweetness and helps the mixture brown lightly in the oven.
- Suet
- Adds fat that enriches the texture and richness of the pudding.
The step that matters
Boiling the rice mixture with milk. The rice must simmer long enough to soften and absorb the milk, and adding water when it looks dry prevents scorching on the base of the pan. Milk scorches easily, so gentle, steady heat matters.
Swap the potato
How well each one fits the dish's main ingredients (rice, milk, sugar):
- Sweet potatofits about as well

- Potatothe original
- Asparagusfits about as well
Fit is the average pairing score against rice, milk, sugar. Candidates are from the same food group and used in at least 100 recipes.
