Add the mayonnaise, sour cream, chipotle peppers, adobo sauce, lime juice, honey, garlic powder, onion powder, salt, and pepper to a blender or food processor.
Blend until smooth and creamy, scraping down the sides as needed.
Serve right away drizzling over fish tacos, or refrigerate for at least 30 minutes for the best flavor.
Notes
Swap light mayonnaise with Greek yogurt for a lighter version.
Use 1 chipotle pepper or just adobo sauce to reduce the heat; blend on a coarse setting for a rustic style.
Store in an airtight container in the fridge for up to 4 days; stir before serving.
Not freezer-friendly—mayonnaise will separate and affect the texture after thawing.
