In a bowl, combine the mayonnaise, sour cream or Greek yogurt, lime juice, minced garlic, chili powder, cumin, cayenne pepper, salt, and pepper.
Whisk the ingredients together until well blended and smooth. Alternatively, you can use a food processor or blender for a smoother consistency.
Taste the sauce and adjust the seasonings according to your preference. Add more lime juice, spices, or salt and pepper as desired.
