Why it works: Flour and raisin match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 9,075 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Potato Flour Pudding, Steamed
Ingredients
Directions
Prepare
Mix potato flour with a little cold milk to form a smooth paste.
Pour boiling milk over the paste and add sugar and beaten eggs.
Butter a round mold and decorate with raisins and candied fruits.
Steam and serve
Pour the pudding mixture into the mold and cover with oiled paper.
Place the mold on an upside-down plate in a saucepan with boiling water, ensuring water does not overflow.
Steam for 1.5 hours until done.
Carefully turn the pudding onto a hot dish and serve with sweet sauce.

Flour and butter barely smell alike, yet cooks put them together in 124,287 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 smooth, sliceable pudding structure.
- Eggs
- Set when heated, giving the pudding its firm, custard-like structure.
- Milk
- Provides liquid that the starch and egg proteins set within, adding softness and richness.
- Sugar
- Adds sweetness and contributes to the pudding's flavour.
The step that matters
Keep the steaming water at a gentle boil without overflow. Steam heats the mold gently and evenly. If the water boils too hard or splashes into the mold, the pudding can become watery or pocked, and uneven heat can leave the centre undercooked or the edges rubbery.
Swap the potato
How well each one fits the dish's main ingredients (milk, flour, sugar, egg, butter, raisin):
- Sweet potatofits better
- Arrowrootfits better
- Shallotfits about as well
- Potatothe original
Fit is the average pairing score against milk, flour, sugar, egg, butter, raisin. Candidates are from the same food group and used in at least 100 recipes.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
