Ingredients
  

Wet Ingredients:
  • ½ cup sour cream
  • ¼ cup mayonnaise
  • 2 tablespoons pickled jalapeños, finely chopped
  • 1 tablespoon pickled jalapeño brine (juice from the jar)
  • 1 tablespoon chipotle sauce (or ½ teaspoon chipotle powder)
  • 1 teaspoon lime juice
Dry Spices:
  • ½ teaspoon garlic powder
  • ½ teaspoon onion powder
  • ½ teaspoon cumin
  • ½ teaspoon smoked paprika
  • ¼ teaspoon cayenne pepper
  • Salt and black pepper to taste

Equipment

  • Medium mixing bowl
  • Small bowl (for dry spices)
  • Whisk or mixing spoon
  • Measuring cups and spoons
  • Sharp knife and cutting board
  • Airtight container or glass jar

Method
 

  1. Finely chop the pickled jalapeños. Reserve 1 tablespoon of brine from the jar.
  2. In a medium bowl, combine sour cream, mayonnaise, chopped jalapeños, jalapeño brine, and chipotle sauce. Stir until smooth.
  3. In a small bowl, mix all dry spices together. Fold the spice blend into the wet mixture gradually.
  4. Add lime juice. Taste and adjust salt, pepper, or cayenne to your preference.
  5. Transfer to an airtight container. Refrigerate for at least 1 to 2 hours before serving. Overnight gives the best flavor.

Notes

  • Don't skip the jalapeño brine. That single tablespoon gives the sauce its tangy, slightly funky depth. Most copycat versions miss this.
  • Overnight chilling makes a real difference. The flavor on day 2 is richer and more balanced than on day 1.
  • Use full-fat sour cream. Low-fat versions produce a thinner texture that doesn't hold up as well.
  • Stores up to 5 days in an airtight container in the refrigerator. Stir before each use.
  • Skip the freezer. Mayo and sour cream separate when frozen and the texture won't recover after thawing.
