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 ↓
Cheese Souffle
Ingredients
Directions
Make the cheese base
Melt the butter in a saucepan over the hot water.
Add the cheese and seasonings, stirring until melted.
Dissolve the baking soda in the hot water and gradually pour it into the cheese mixture.
Beat the egg yolks until light, adding a little cold water, then stir into the cheese mixture.
Once smooth and creamy, mix in the Worcestershire sauce and lemon juice.
Finish and serve
Whip the egg whites until stiff and fold them into the mixture.
Serve immediately on toast.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cheese
- Melts into the base to give the soufflé its rich flavour and body.
- Eggs
- Yolks enrich and bind the base, while whipped whites lift and set the soufflé.
- Butter
- Adds richness and helps form a smooth, creamy base with the cheese.
- Baking soda
- Reacts with the acidic cheese and lemon juice to help the mixture rise and lighten.
The step that matters
Folding in the egg whites. Whipped whites hold the air that makes the soufflé rise. Folding gently keeps that air in, while stirring vigorously would deflate the mixture.
