Cut the avocados in half, remove the pits, and scoop the flesh into a blender or food processor.

Add the sour cream (or Greek yogurt), fresh lime juice, minced garlic, and cilantro, cumin, and kosher salt.

Blend the mixture until smooth and creamy. If the mixture is too thick, you can add a little more lime juice, one tablespoon at a time, until you reach the desired consistency.

Taste for salt and add as desired. Blend again briefly to combine.
