2In a saucepan, combine the shallots, mignonette pepper, and vinegar. Reduce the mixture over heat until it reaches a compote-like consistency.
3Add the white wine and the egg yolks. Whisk constantly over medium heat to emulsify without cooking the eggs; remove from heat occasionally if the saucepan gets too hot.
4Once the mixture is creamy and smooth, mount the sauce by whisking in the cold cubes of butter gradually.
5Fold in the chopped tarragon delicately.

Traditionally, this sauce uses tarragon and chervil, but the creator prefers just tarragon.
