Ingredients
Scale
- 1/2 cup quality mayonnaise (full fat recommended)
- 1 medium jalapeño, stem removed and roughly chopped
- 1/4 cup fresh cilantro, packed
- 2 tablespoons fresh lime juice
- 1 small clove garlic, peeled
- 1/2 teaspoon kosher salt
- 1 teaspoon distilled white vinegar
- 2 tablespoons cold water (or more, for desired consistency)
Instructions
- Step 1: Combine the mayonnaise, chopped jalapeño, cilantro, lime juice, garlic clove, salt, and white vinegar in the jar of a high-speed blender or a small food processor.
- Step 2: Secure the lid and begin blending on low speed, gradually increasing to high. Blend continuously, scraping down the sides as necessary, until the sauce is completely smooth and uniform in color.
- Step 3: While the blender is running, slowly drizzle in the 2 tablespoons of cold water to help the ingredients fully incorporate and thin the mixture slightly, achieving a creamy, pourable consistency.
- Step 4: Stop the blender, taste the sauce, and adjust seasonings. Add more salt or lime juice if needed for flavor, or additional water (1 tablespoon at a time) if a thinner texture is desired.
- Step 5: Pour the finished sauce into an airtight container or jar. Refrigerate for at least 30 minutes before serving. Chilling allows the flavors to meld and the sauce to set to the ideal restaurant thickness.
Notes
- Keep this sauce tightly sealed in the refrigerator for up to one week; the fresh cilantro, jalapeño, and mayonnaise mean it is best enjoyed quickly.
- Do not skip the 30-minute refrigeration step; chilling is crucial as it allows the texture to set to the ideal restaurant-style thickness and lets the spicy and tangy flavors fully meld.
- For maximum emulsion stability and the perfect creamy texture, ensure you use a quality full-fat mayonnaise and gradually stream in the cold water while the blender is running on high speed.
- While perfect for street tacos, try using this vibrant sauce as a creamy, zesty dressing over grilled corn salad, air-fried potato wedges, or blackened fish fillets.
