Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Anchovies
- Break down during boiling to deliver a deep, salty, savoury backbone to the sauce.
- Shallots
- Add aromatic sweetness and depth as they soften and release flavour into the liquid.
- White wine
- Provides acidity and liquid that extracts flavour from the solids during reduction.
- Red wine
- Adds acidity, colour and tannin-driven body to the reduced sauce.
- Lemon
- Contributes acidity and bright citrus aroma to balance the salty anchovies.
The step that matters
Boil until the mixture reduces to 1 quart. Reducing concentrates the salt, acid and flavour of the liquid. Stopping too early leaves the sauce weak and thin, while over-reducing makes it overly salty and harsh.
