Why it works: Sugar and egg are a kitchen classic. They rank in the top 21% of all ingredient pairs, and cooks put them together in 122,807 recipes. Both carry 2-nonenal, which smells fatty, green. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Clarified sugar
- Cooked to a barley sugar consistency, it forms the hard, glassy body of the candy.
- Egg white
- Whisked with fine sugar and stirred in, it adds a light texture and helps the mixture set.
- Oil of peppermint
- Provides the characteristic peppermint aroma and flavour.
The step that matters
Stirring in the egg mixture quickly. Once the cooked sugar begins to cool and thicken, it sets quickly. Fast, thorough stirring keeps the egg mixture evenly distributed before the candy firms up and becomes uneven.
