Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Cucumbers
Provide the bulk of the sauce and a fresh, watery texture once drained.
Whipped cream
Adds richness and a smooth, creamy body to the sauce.
Vinegar
Adds acidity that brightens the sauce and balances the richness.
Tarragon
Contributes a distinct anise-like aroma that flavours the sauce.

The step that matters

Drain the pulp thoroughly. Cucumber is mostly water. Leftover liquid would thin the sauce and dilute the vinegar and seasoning, so the pulp should be well drained before mixing.

Swap the onion

How well each one fits the dish's main ingredients (cucumber, tarragon, pepper, vinegar, cream):

  1. Lettucefits better
  2. Mustardfits better
  3. Shallotfits better
