Ingredients

Scale
  • Spices:

    • 1 tablespoon chili powder
    • 1 teaspoon smoked paprika
    • 1 teaspoon ground cumin
    • 1 teaspoon garlic powder
    • ½ teaspoon dried oregano
    • ½ teaspoon salt (adjust to taste)
    • ¼ teaspoon black pepper
  • Liquids:

    • Juice of 2 limes (about ¼ cup)
    • 2 tablespoons avocado oil (or olive oil)
    • ¼ cup water
  • Sweetener & Extras:

    • 1 teaspoon honey (or brown sugar)
    • 1 teaspoon apple cider vinegar (for extra tang)
    • 1 chipotle pepper in adobo sauce (optional, for smoky heat)

Instructions

  1. Mix the Dry Ingredients: In a small bowl, whisk together the chili powder, smoked paprika, cumin, garlic powder, oregano, salt, and black pepper.

  2. Add the Wet Ingredients: Pour in the lime juice, avocado oil, and water, whisking until smooth.

  3. Incorporate Sweetness & Acidity: Stir in the honey and apple cider vinegar, ensuring everything is well combined.

  4. Optional Smoky Heat: If using, finely chop the chipotle pepper and mix it into the sauce for an extra smoky-spicy kick.

  5. Adjust Consistency: If the sauce is too thick, add a tablespoon of water at a time until it reaches the desired texture.

  6. Store & Use: Transfer the sauce to an airtight container and refrigerate for up to 7 days. Shake or stir before use.

Notes

  • For a richer sauce, add 2 tablespoons of tomato paste.
  • For a creamier version, mix in 2 tablespoons of Greek yogurt or sour cream.
  • To make it spicier, add extra chipotle peppers or a dash of cayenne pepper.
