Why it works: Pepper and lemon 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 ↓
Fish Soufele
Ingredients
Directions
Make the base
In a pan, melt the butter and mix in the flour over medium heat until smooth.
Add the fish stock or milk and stir until free from lumps.
Prepare the fish mixture
Finely shred the uncooked fish and add it to the sauce along with pepper, salt, lemon juice, and egg yolks.
Pound the mixture in a mortar and then rub it through a sieve.
Beat the egg whites to stiff peaks and gently fold them into the mixture.
Steam and serve
Pour the mixture into a greased basin, filling it halfway, and cover with greased paper.
Steam for 20 minutes until firm.
Carefully turn out onto a plate and serve.

Flour and butter barely smell alike, yet cooks put them together in 124,287 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 whites
- Whipped to stiff peaks, they trap air that lifts the soufflé as it steams.
- Egg yolks
- Enrich the sauce and help set the mixture as it cooks, adding richness and body.
- Flour
- Thickens the butter and stock into a smooth sauce base that holds the fish.
- Butter
- Forms the roux with the flour and adds richness and flavour to the base.
- Fish
- Provides the main flavour and the bulk of the soufflé's body.
The step that matters
Folding in the egg whites. Whites must be beaten to stiff peaks and folded in gently. Stirring or deflating them loses the trapped air, so the soufflé will not rise and turn out light.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
