Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Carries the cooking of the aromatics and adds richness to the sauce.
- Shallots or onions
- Browning them adds savoury depth and a sweet base flavour to the sauce.
- Mushrooms
- Soften as they cook, releasing moisture and adding earthy body to the sauce.
- Strained tomato sauce
- Forms the main body of the sauce and supplies its acidity and tomato flavour.
- Lemon juice
- Adds acidity that brightens the tomato and balances the richness of the butter.
The step that matters
Frying the shallots or onions until brown. Browning develops deep, savoury flavour through the Maillard reaction. Pale or under-browned onions leave the sauce tasting flat, while over-browning can turn them bitter.
