Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Anchovies
- Dissolve into the liquid to add deep savoury, salty umami flavour.
- Shallots
- Add aromatic sharpness and sweetness that mellows during simmering.
- Walnut pickle
- Provides the main concentrated flavour base for the sauce.
- Port wine
- Adds sweetness and body, with acidity that rounds the savoury flavours.
- Mushroom catsup
- Contributes earthy, savoury depth typical of umami-rich condiments.
- Soy sauce
- Adds salty, fermented savoury flavour and colour to the sauce.
The step that matters
Simmering. Simmering gently for the stated time concentrates and blends the flavours. Boiling hard can evaporate liquid too fast and make the sauce harsh, while stopping early leaves the flavours underdeveloped.
