¼cupwater, or more depending on desired consistency
Instructions
Mince the Cilantro and garlic before putting them in the food processor. The sauce will be a lot smoother if you do this.
Combine yogurt and avocado in the food processor and process until smooth.
Add the lime, cilantro, garlic, and seasonings. Blend until completely combined.
Add up to a ¼ cup of water as necessary to thin the crema. Thinner cremas can be used to top tacos while thicker versions can be great for burgers and sandwiches.
Notes
The amount of water you will need depends on how juicy the lime is and what you're serving the crema with. If I'm going to drizzle the crema over some tacos I'll want it thinner than if I'm spreading it on toast or putting it on a burger
I always mince ingredients like garlic and cilantro before putting them in the food processor. You'll get a more consistent cut this way and won't have chunks of garlic or cilantro leaves weaved through the crema.
