Why it works: Lemon and pepper match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and cooks put them together in 27,047 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- American cheese
- Melts into a smooth, creamy base that gives the souffle its flavour.
- Eggs
- Yolks enrich and thicken the base, while whipped whites trap air so the souffle can rise.
- Baking soda
- Raises the pH of the cheese, helping it melt smoothly and stay creamy.
- Butter
- Adds fat for richness and helps the cheese melt into a smooth mixture.
- Lemon juice
- Adds acidity that balances the rich cheese flavour.
The step that matters
Fold in the whipped egg whites. Folding gently keeps the air trapped in the whites. That trapped air is what lifts the souffle, so stirring or deflating the mixture will leave it flat and dense.
