Start by assembling all your ingredients on the counter. This makes it easier to see what you have and what you need.
Chop the pickled jalapeño peppers into small pieces. This allows them to distribute evenly throughout the dip, ensuring every bite has that spicy goodness.
In your mixing bowl, combine the sour cream and mayonnaise. Use a whisk or spoon to blend them together until smooth and creamy.
Stir in the dry ranch dressing mix, tomatillo salsa, chopped jalapeños, cilantro leaves, and fresh lime juice. Make sure everything is well incorporated.
Give your dip a taste test. Depending on your preference, you may want to add more lime juice or jalapeños for an extra kick.
Refrigerate the dip for at least 30 minutes before serving. This allows the flavors to meld together beautifully.
