Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eschalots
- Provide a mild onion-like aromatic base that flavours the reduction.
- Wine vinegar
- Adds acidity that sharpens the sauce and balances the rich butter and cream.
- Veloute
- Supplies the sauce base body, thickening it as it boils down.
- Fresh butter
- Adds fat that gives the finished sauce a smooth, rounded texture.
- Fresh cream
- Adds richness and a silky texture that softens the sharpness of the vinegar.
The step that matters
Boiling the mixture down. Reducing the vinegar and herbs concentrates their flavour and acidity. Boiling too hard or too long can over-reduce the sauce and make it sharp, so the flavour must be judged as it thickens.
Swap the spinach
How well each one fits the dish's main ingredients (chervil, tarragon, wine, vinegar, pepper, butter, cream):
