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

What each ingredient does

Cucumber
Provides the fresh, watery bulk and mild flavour of the sauce.
Whipped cream
Adds fat and a light, airy body that makes the sauce creamy and smooth.
Tarragon vinegar
Adds acidity that brightens the sauce and balances the richness of the cream.
Onion juice
Adds a pungent aromatic note that gives the sauce savoury depth.

The step that matters

Fold in the whipped cream gently. Whipped cream holds air in a fragile network of fat globules. Overmixing can deflate it or turn it grainy, leaving the sauce thin or dense. Mix only until the ingredients are evenly combined.

Swap the onion

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