How to Prepare Cold Mayonnaise-sauce, a LA Ragivote
Ingredients
Directions
Prepare the herbs
Boil 2 quarts of water with a little coarse sea salt.
Add tarragon, pimpernel, chives, chervil, and parsley; boil for 5 minutes.
Drain the herbs, plunge them into the liquid, and boil for 2 minutes.
Press out the moisture, then pound the herbs with anchovy fillets, gherkin, capers, and shallots until it forms a paste.
Finish the sauce
Pass the mixture through a fine sieve and mix it into prepared mayonnaise sauce.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Anchovy fillets
- Add salty, savoury depth that rounds out the herb flavours.
- Capers
- Contribute sharp acidity that cuts through the richness of the mayonnaise.
- Gherkin
- Adds tangy acidity and a crisp, pickled note to the sauce.
- Shallots
- Provide mild aromatic sharpness that blends into the paste.
- Mayonnaise sauce with eggs
- Provides the fatty, emulsified base that carries the flavours and gives a creamy texture.
The step that matters
Press out the moisture from the herbs. Blanched herbs hold a lot of water; if they are not pressed dry, the paste stays loose and dilutes the mayonnaise, making the sauce thin and watery.
