Sugar and lemon barely smell alike, yet cooks put them together in 53,532 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
- Egg yolks
- Thicken the custard base and add richness as they cook gently.
- Gelatine
- Sets the pudding so it holds its shape when turned out.
- Egg whites
- Whipped to stiff peaks, they lighten the mixture and give it an airy texture.
- Milk
- Forms the creamy base that the yolks thicken into a custard.
- Sugar
- Sweetens the pudding and balances the citrus acidity.
The step that matters
Cook gently without boiling. Egg yolks thicken as they heat, but boiling can curdle them and leave a grainy texture. Gentle heat also lets the gelatine dissolve fully so the pudding sets evenly.
Swap the orange
How well each one fits the dish's main ingredients (milk, egg, sugar, lemon):
- Vanillafits better
- Orangethe original
- Figfits about as well
- Blueberryfits about as well
Fit is the average pairing score against milk, egg, sugar, lemon. Candidates are from the same food group and used in at least 100 recipes.
