| 1 | Prepare 250 g mayonnaise and add 2 tablespoons vinegar to it, stirring with a spoon. |  |
| 2 | Remove the leaves from the tarragon and chervil, then prepare 1 shallot. |  |
| 3 | Chop the chervil, tarragon, and shallot. |  |
| 4 | Add them to the vinegar-based mayonnaise (which is actually a rémoulade sauce ), mix well, and then check the seasoning.
If possible, let it rest in the fridge for 1 hour or more so that the flavors of the herbs infuse the mayonnaise. |  |
| 5 | Your mayonnaise-Béarnaise sauce is ready; it goes very well with meat, fish, or cooked or raw vegetables. |  |
You can easily adjust the amounts of herbs, shallots, and vinegar to suit your taste.
You can replace half of the vinegar with dry white wine.
