Ingredients
Directions
In a small bowl, mix the mustard with a few drops of cold water.
Slowly add oil while stirring vigorously until it thickens.
If it thickens too much, thin it with lemon juice or vinegar.
Add tarragon vinegar if desired.
Season with coarse sea salt to taste.

What each ingredient does
- Plain mustard
- Helps emulsify the oil and water so the sauce holds together and thickens.
- Oil
- Forms the thick body of the sauce as it is whisked into the mustard base.
- Lemon juice or vinegar
- Thins the sauce when it gets too thick and adds a sharp, bright acidity.
The step that matters
Slowly add oil while stirring vigorously. Oil must be added gradually and whisked in so droplets disperse finely in the water-based mixture. Adding it too fast can break the emulsion, leaving a runny, separated sauce that will not thicken.
