In a small bowl or jar, whisk together the minced shallot, apple cider vinegar, Dijon mustard, maple syrup, and salt until combined. *
Slowly drizzle in the olive oil while whisking continuously until the vinaigrette is smooth and emulsified.*
Taste and adjust seasoning — add a touch more vinegar for brightness or maple syrup for sweetness.
Let the dressing rest for 10 minutes before serving to allow the shallot flavor to mellow.
