In a small bowl, whisk together the vinegar, honey, mustard, thyme (if using), salt, and pepper. Slowly add the olive oil, whisking constantly and vigorously as you go.
Alternatively, combine all the ingredients in a small jar, such as an empty mustard jar, close the lid tightly, and shake like crazy until well combined.
Taste and add a little more vinegar if you prefer a sharper vinaigrette.
