Why it works: Corn and flour are a kitchen classic. They rank in the top 13% of all ingredient pairs, and cooks put them together in 6,165 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Thicken the custard as they set and add richness to the pudding.
- Egg whites
- Fold in at the end to lighten the pudding and give it an airy texture.
- Corn starch
- Thickens the custard as it heats with the boiling water.
- Flour
- Adds body and helps thicken the custard alongside the corn starch.
- Sugar
- Sweetens the pudding and balances the sharpness of the lemon.
- Lemon juice
- Adds acidity and bright lemon flavour to the custard.
The step that matters
Cook in a double boiler until it begins to thicken. Starch thickens only when heated enough to swell its granules, but overheating can scramble the egg yolks and make the custard grainy. Gentle, indirect heat and steady stirring keep it smooth.
