Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eels
- Give the sauce its main fish flavour as they simmer in the stock.
- Veal
- Adds meaty body and savoury depth to the sauce during the long simmer.
- Bacon
- Contributes salty, smoky savour that flavours the liquid as it cooks.
- Onions
- Add aromatic sweetness and background flavour as they cook down.
- White wine
- Adds acidity and aroma that brighten the rich, savoury liquid.
- Broth
- Forms the liquid base that carries and blends all the flavours.
The step that matters
Skim well. Skimming removes fat and fine impurities that rise during simmering. Removing them keeps the sauce clear and stops it tasting greasy or muddy.
