Instructions

• Combine 1 ripe avocado (peeled, pitted, and roughly chopped), 1 large handful fresh cilantro (finely chopped), 3 tablespoons fresh lime juice, 3 tablespoons mayonnaise, and ½ teaspoon kosher salt in the bowl of a food processor.
• Purée until smooth, stopping once or twice to scrape down the sides with a spatula so all ingredients are evenly blended.
• If the sauce is too thick, thin it by adding additional fresh lime juice or mayonnaise, ½ tablespoon at a time; process briefly after each addition until you reach the desired consistency.
• Taste and add more kosher salt if needed, processing or stirring briefly to combine.
• If you do not have a food processor: place the avocado, cilantro, lime juice, mayonnaise, and salt in a medium bowl and mash with a fork or potato masher until smooth and well combined, scraping the bowl as needed.
• For the mashed method, thin with additional fresh lime juice or mayonnaise, ½ tablespoon at a time, and taste-adjust salt as in steps 3–4.
