For the vinaigrette, combine all ingredients in pint mason jar. Seal jar and shake well to emulsify. Taste mixture and see if it is missing anything. You want the vinaigrette to be potent but not offensive. You are looking for the right balance of sweet, salty, tangy and acidic. For more tang add a bit more Dijon mustard. If it's too acidic, add more sweetener like honey or maple. If you can't really taste the vinaigrette then you most likely need more salt. You can use a lettuce or asparagus piece to dip into the vinaigrette to really see how the dressing will taste on the salad.
