Mix base ingredients: Zest one lemon and juice all 3 small lemons. In a medium sized bowl, whisk the lemon juice and zest with 1 tablespoon shallots, 1 tablespoon Dijon mustard, 1 tablespoon fresh herbs, 1/2 teaspoon salt and Fresh ground pepper.
Emulsify: While whisking rapidly with one hand, slowly pour all of the 1/4 cup extra virgin olive oil into the mixture. Continue whisking until everything is well mixed.
Once fully emulsified, taste the dressing and add additional salt, if desired. The vinaigrette should taste salty at first and then have a tart finish.
