Add all ingredients to a mixing bowl and stir to combine.
Use immediately or, for best flavor, refrigerate the the dressing for 2 to 3 hours to allow the flavors to meld.
For more heat, add more chipotle powder (though you will also add more smoky flavor). If you want more heat without the smokiness, add a dash of cayenne pepper powder to the mix. Cayenne powder is more neutral in flavor, though it's much hotter (30,000 - 50,000 Scoville heat units) than chipotle powder (2,500 - 8,000 SHU). Add it sparingly until you reach the heat level you prefer.
