Combine all of the ingredients in a jar with a tight-fitting lid or in a medium bowl.
Vigorously shake or whisk until completely combined.
Serve immediately on a salad, or store in an airtight container in the fridge for up to 1 week. The ingredients will separate as the dressing sits, so shake or whisk again before using.
Notes
Look for red pepper jelly for a mild flavor or try a hot pepper jelly if you like a spicy taste.
Taste the vinaigrette before serving and adjust the seasoning as needed. It might need a little bit more salt or some ground black pepper. You might also want to add dried herbs or chopped fresh herbs, minced shallots, garlic or garlic powder, or cayenne or red pepper flakes (to make it even spicier).
Scale this recipe to make more or less. For instance, if you just want enough for one salad, you can cut all of the ingredients in half. Alternatively, you can prepare a larger batch by doubling the ingredients and keep the extra dressing in your fridge to enjoy all week.
If you have leftover vinaigrette, use the pepper jelly dressing as a marinade or glaze for grilled chicken or grilled shrimp. It creates a sweet and spicy char!
