For an extra layer of flavor, lightly toast the sesame oil in a saucepan over low heat, let it cool completely before using it in the recipe. Adjust the sweetness and acidity to your liking by adding more maple syrup or rice vinegar, respectively. The vinaigrette can be stored in an airtight container in the refrigerator for up to a week. Shake well before each use as the ingredients may separate over time.
