Easy Homemade Mexican Crema made with just 4 ingredients and designed for a squeeze bottle. It’s rich, tangy, velvety-smooth, and perfect for drizzling over tacos, nachos, enchiladas, burrito bowls, and more.
Combine heavy cream and cultured buttermilk in a clean bowl (or a 16 oz. Oxo Squeeze Bottle if using). Cover loosely and let rest at room temperature for approximately 12–24 hours to culture and thicken.
The next day, add the salt and lime juice, stirring (or shaking if using a squeeze bottle) to combine. Taste and adjust the salt and lime juice if needed.
Refrigerate until completely cool, approximately 2–3 hours or overnight.
Notes
Use cultured buttermilk, not milk mixed with lemon juice or vinegar (or other buttermilk substitutes). The live cultures are what thicken the cream and develop flavor.
Use a very clean jar, bowl, or squeeze bottle since the crema rests at room temperature while it thickens. Clean equipment helps keep the flavor fresh and lets the cultured buttermilk do its job.
The finished crema should be thinner than sour cream but thick enough to coat a spoon. If it gets too thick, stir or shake in a small splash of lime juice, buttermilk, or heavy cream.
