How to Make Mexican Crema with Sour Cream?
Making Mexican crema at home using sour cream is surprisingly easy. This article shows you how to create a delicious, tangy, and pourable substitute by simply thinning sour cream with buttermilk or whole milk and a touch of lime juice and salt.
Understanding Mexican Crema
Mexican crema (crema Mexicana) is a staple in Mexican cuisine, used to top everything from tacos and enchiladas to soups and desserts. It’s distinct from sour cream or crème fraîche, offering a thinner, tangier, and slightly richer flavor profile. Traditional Mexican crema is made from cultured heavy cream, resulting in a looser consistency and a sharper tang due to the different bacterial cultures used. However, achieving a similar result at home using readily available ingredients like sour cream is perfectly feasible and incredibly convenient.
Why Make Your Own?
There are several compelling reasons to make your own Mexican crema:
- Availability: Mexican crema isn’t always available in regular grocery stores, especially in some regions.
- Cost: Homemade versions are often more economical than store-bought.
- Customization: You can adjust the consistency and flavor to your personal preferences.
- Freshness: You control the ingredients and ensure freshness.
- Versatility: It adds a delicious touch to a wide variety of dishes.
The Secret: Thinning Sour Cream
The key to making authentic-tasting Mexican crema with sour cream lies in thinning it to the right consistency. Sour cream is naturally thicker than Mexican crema, so adding liquid is essential. The most common and effective liquids are:
- Buttermilk: This adds a subtle tang that complements the sour cream. It’s generally preferred for a more authentic flavor.
- Whole Milk: A good alternative if you don’t have buttermilk. It creates a slightly less tangy crema.
- Lime Juice: A small amount adds brightness and enhances the overall flavor.
- Salt: Balances the flavors and enhances the tanginess.
The Process: Step-by-Step Guide
Here’s a simple recipe to guide you through the process:
- Combine Ingredients: In a bowl, combine 1 cup of full-fat sour cream, 2-4 tablespoons of buttermilk or whole milk, 1 tablespoon of lime juice, and a pinch of salt.
- Whisk: Whisk the ingredients together until smooth and well combined. Start with the smaller amount of liquid and add more until you reach your desired consistency. The crema should be pourable but not too thin.
- Taste and Adjust: Taste the crema and adjust the seasoning as needed. Add more lime juice for extra tang, or more salt to balance the flavors.
- Chill: Cover the bowl and refrigerate for at least 30 minutes to allow the flavors to meld and the crema to thicken slightly.
- Serve: Drizzle over your favorite Mexican dishes or use as a dipping sauce.
Tips for Achieving Perfect Crema
- Use Full-Fat Sour Cream: This will result in a richer and more flavorful crema.
- Start Slowly with the Liquid: It’s easier to add more liquid than to try to thicken the mixture if you add too much.
- Allow Time for the Flavors to Meld: Chilling the crema allows the flavors to fully develop.
- Adjust to Your Taste: Don’t be afraid to experiment with the amount of liquid, lime juice, and salt to create a crema that perfectly suits your palate.
Common Mistakes to Avoid
- Using Low-Fat Sour Cream: This will result in a watery and less flavorful crema.
- Adding Too Much Liquid at Once: This can make the crema too thin.
- Skipping the Chilling Step: This prevents the flavors from fully developing.
- Over-Whisking: This can cause the sour cream to become too thin or separate. Gentle whisking is all that’s needed.

Frequently Asked Questions (FAQs)
Can I use Greek yogurt instead of sour cream?
Yes, you can use Greek yogurt, but the result will be slightly tangier and less rich. Make sure to use full-fat Greek yogurt and adjust the amount of liquid accordingly. You may need to add a little more buttermilk or milk to achieve the desired consistency.
How long does homemade Mexican crema last?
Homemade Mexican crema will typically last for 3-5 days in the refrigerator, stored in an airtight container. Always check for any signs of spoilage, such as an off odor or discoloration, before using.
Can I freeze Mexican crema?
Freezing Mexican crema is not recommended, as it can alter the texture and cause it to become grainy upon thawing. It’s best to make it fresh as needed.
What can I use instead of buttermilk?
If you don’t have buttermilk, you can use whole milk mixed with a teaspoon of lemon juice or white vinegar. Let it sit for 5 minutes before using to allow the milk to sour slightly. You can also use half-and-half for a richer result.
Is there a vegan alternative?
Yes! You can use cashew cream or full-fat coconut cream as a base for a vegan Mexican crema. Blend the cashew cream or coconut cream with lime juice, salt, and a small amount of plant-based milk to achieve the desired consistency.
How can I make the crema thicker?
If your crema is too thin, you can add a small amount of cornstarch slurry (1 teaspoon of cornstarch mixed with 1 tablespoon of cold water) to the mixture and heat it gently on the stovetop until it thickens. Be careful not to boil it.
What dishes can I use Mexican crema on?
Mexican crema is incredibly versatile and can be used on a wide range of dishes, including tacos, enchiladas, quesadillas, nachos, soups, stews, salads, grilled corn, and even desserts.
Can I add other flavorings to the crema?
Absolutely! Feel free to experiment with other flavorings, such as chopped cilantro, minced garlic, chili powder, or smoked paprika, to create your own unique variations.
Is Mexican crema the same as crème fraîche?
No, Mexican crema and crème fraîche are similar but not identical. Crème fraîche is generally richer and less tangy than Mexican crema. Mexican crema also tends to be thinner in consistency.
What does “full-fat” sour cream mean?
Full-fat sour cream simply refers to sour cream made with whole milk. This results in a richer flavor and a creamier texture compared to low-fat or fat-free varieties.
Why is my crema lumpy?
Lumpy crema can result from over-whisking or using sour cream that is too cold. To prevent this, ensure your sour cream is at room temperature before mixing and whisk gently.
Can I use this crema as a substitute for sour cream in baking?
Yes, you can use this homemade Mexican crema as a substitute for sour cream in baking, but keep in mind that it will add a slightly tangier flavor to your baked goods. Adjust the amount of liquid in your recipe accordingly.
