Fresh Homemade Mexican Crema (Made With Just 2 Ingredients!)

Forget topping your favorite Mexican meals with a dollop of store-bought sour cream. Instead, opt for a fresher, more authentic creamy condiment: Mexican crema.

Homemade Mexican Crema

What is Mexican crema?

Mexican crema, also called Mexican sour cream, is similar to the French crème fraîche — a luscious, thickened cream with a bit of a sour flavor. Both Mexican crema and crème fraîche are different from American sour cream, which tends to be thicker (and, if bought from the store, full of preservatives).

You can buy Mexican crema or crème fraîche at the grocery store, but the pre-packaged stuff tends to be artificially thickened and lacks the fresh, nutty flavor of homemade crema.

Homemade Mexican Crema

That’s why culinary experts like renowned chef Rick Bayless make their own crema at home: It produces a better flavor and texture, and it couldn’t be easier. Today, we’re sharing Rick’s method for making homemade crema in just a few simple steps.

Homemade crema recipe

When making crema at home, you start with heavy cream and add live cultures by mixing in sour cream or buttermilk.

Two Ingredients for Mexican Crema

You only need two ingredients:

Heavy cream, and sour cream OR buttermilk with active cultures. The active cultures are key: Since the cream’s naturally occurring bacteria (which would thicken the cream) are removed during pasteurization, we need to re-introduce cultures to thicken it up.


Watch this video, or check out the recipe below.

Step 1:

Pouring Heavy Cream into Pot

Pour the heavy cream into a small sauce pan, and warm over medium just to “body temperature.” If it gets too warm, it’ll kill active cultures in the cream, so err on the side of caution.

Step 2:

Add Sour Cream to Pot

Add spoonful of active sour cream or buttermilk, and whisk until thoroughly incorporated.

Step 3:

Sour Cream Mixture in Mason Jar

Pour the cream mixture into a jar. Put the lid on, but don’t tighten it all the way; leave it ajar to allow for a little air circulation.

Step 4:

Mexican Crema in Jar on Counter

Let the jar stand at room temperature for about 12 hours, or until noticeably thicker. Then, put it in the fridge and chill to your liking.

After refrigerating, the cream will be thick, luscious and a little tangy. Serve it with tacos, enchiladas or other Mexican favorites in place of sour cream. Store in the fridge for 7-10 days. So little effort, such delicious results!
