Begin by slicing the avocados in half, carefully removing the pit. Use a spoon to scoop the creamy flesh into the bowl of a food processor.
Next, incorporate the sour cream (or Greek yogurt) along with the fresh lime juice and lime zest. Add the minced garlic, ground cumin, and sprinkle a pinch of salt and pepper into the mix.
Secure the lid on the food processor and blend the ingredients on high speed for about 30 seconds, or until the mixture is smooth and creamy. If the crema is thicker than desired, drizzle in a tablespoon of water and blend again until you achieve your preferred consistency.
Taste the crema and fine-tune the seasoning as needed. Add more salt, pepper, or a splash of lime juice according to your flavor preference.
Carefully transfer the zesty avocado lime crema into a serving bowl and cover it with plastic wrap. Place it in the refrigerator for approximately 30 minutes to allow the flavors to blend beautifully.
Just before serving, garnish the crema with fresh cilantro leaves for a vibrant touch and an extra layer of flavor.
Notes
Substitute sour cream with Greek yogurt for a healthier option.
