Why it works: Shallot and parsley match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 3,737 recipes. Both carry 2,4-decadienal, which smells seaweed. The science ↓
Eggs, Souffle
Ingredients
Directions
Make the base
Combine egg yolks and butter in a small saucepan.
Fry sliced shallots in a separate pan until golden.
Add shallots, mushrooms, parsley, pepper, and salt to the saucepan with yolks and butter.
Place the saucepan in a larger pan of boiling water and stir until the mixture thickens.
Remove from heat, whisk the mixture for 1–2 minutes, and let it cool.
Assemble and bake
Whisk egg whites until firm.
Fold the beaten egg whites into the cooled yolk mixture.
Pour the mixture into a soufflé dish or small ramekins.
Place the dish in a covered saucepan and add boiling water until it nearly reaches the edges.
Once the water simmers, remove from heat and let the soufflé sit for about 10 minutes before removing the cover.
Serve
Serve immediately.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Whipped whites trap air for lift; yolks thicken and enrich the base.
- Butter
- Adds richness and fat that carries flavour and softens the texture.
- Shallot
- Adds mild savoury sweetness when fried until golden.
- Dried mushrooms
- Adds earthy, savoury depth to the custard.
The step that matters
Fold the whites in gently. Fold the beaten whites in gently, in portions, rather than stirring. Their trapped air is what makes the soufflé rise, and vigorous mixing knocks it out, leaving a dense result.
Swap the shallot
How well each one fits the dish's main ingredients (egg, butter, mushroom, parsley, pepper):
- Shallotthe original
- Capsicumfits about as well
- Spinachfits about as well
- Chivefits less well
Fit is the average pairing score against egg, butter, mushroom, parsley, pepper. Candidates are from the same food group and used in at least 100 recipes.
