This Crema recipe consists of 3 simple ingredients. Just stir sour cream, heavy whipping cream, and freshly squeezed lime juice together and let sit at room temperature for a couple of hours.
Mix all of the ingredients together. Make sure that there aren't any chunks of sour cream remaining. But this isn't rocket science. Really, just mix and set aside!
Let sit at room temperature for 2-3 hours and then serve or refrigerate.The citrus in the lime juice will keep the crema from going bad. Just make sure to refrigerate it after a couple of hours. You're looking for it to be a little bit sour, but not spoiled because it will eventually go bad!
Tips, Tricks, & Notes
You can mix around a little bit with the ratio of sour cream-to-whipping cream. The one-to-one ratio will be a little bit more on the liquid side. I've definitely had crema that's less of a liquid. You can add a higher ratio of sour cream-to-heavy whipping cream if you want it to be a little bit thicker.
