Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Yolks enrich and set the custard, while beaten whites trap air so the soufflé rises.
- Butter
- Adds fat for richness, flavor and a tender texture.
- Flour
- Thickens the hot milk into a stable, spoonable base.
- Milk
- Forms the liquid body of the custard base once cooked with the flour.
- Powdered sugar
- Sweetens the custard and balances the richness of the eggs.
The step that matters
Fold in the beaten egg whites gently once the base has cooled. Beaten whites hold air bubbles that make the soufflé rise. Folding into a hot base can deflate them, and overmixing knocks out air, leaving a dense result.
“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.
