Lemon and sugar 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
- Lemons
- Provide acidity and fragrant oils from the rinds and juice that brighten the punch.
- Lump sugar
- Sweetens the punch and draws oils from the lemon rinds as it is rubbed in.
- Rum or brandy
- Adds the spirit base and aroma that give the punch its character.
The step that matters
Stir continuously while adding the water. Pouring boiling water into the mixture without stirring can leave sugar undissolved and uneven in flavour. Constant stirring disperses the hot water and helps the sugar dissolve evenly.
