Make Ahead and Storage
Storing Leftovers
Once you’ve made this Lime Crema (Fish Taco Sauce) Recipe, store any leftovers in an airtight container in the refrigerator. It will stay fresh and delicious for up to 3-4 days. Always give it a quick stir before serving, as ingredients may separate slightly.
Freezing
Freezing is not recommended for this sauce because the crema or sour cream base can separate and become grainy when thawed. For the best texture and flavor, enjoy it fresh or refrigerated within a few days.
Reheating
This lime crema is best served cold or at room temperature. If you find it too thick from chilling, just stir in a tiny splash of water or lime juice to loosen it up. Avoid heating it on the stove or microwave, as this can alter its creamy texture.
FAQs

The garlic is finely minced and used sparingly, so it adds just a mild savoriness that balances the acidity without overpowering the sauce.
Is this sauce only good with fish tacos?
Not at all! While it’s famously paired with fish tacos, this lime crema shines as a dip, dressing, or topping for all sorts of dishes like grilled chicken, roasted veggies, or even salads.
