Tarragon Mayonnaise

Combine mayonnaise and finely chopped fresh tarragon in a medium bowl, stirring until the tarragon is evenly distributed throughout.

Add finely chopped white onion to the mixture and fold gently to incorporate without breaking down the texture.

Pour fresh lemon juice into the bowl and stir thoroughly to blend the acidic element evenly.

Sprinkle a pinch of cayenne pepper into the mayonnaise and mix well to distribute the heat evenly.

Taste the mixture and season with sea salt as needed, stirring after each addition until the desired seasoning is reached.

Transfer the tarragon mayonnaise to a serving bowl or storage container and refrigerate until ready to serve, allowing the flavors to meld for at least 15 minutes.
