Elevate your fish tacos with a creamy, tangy, and slightly spicy sauce that perfectly complements the flavors of the seafood. This sauce is quick to make and adds a delightful zing to your tacos, making them irresistible.
If you don't usually stock sriracha in your pantry, it's a spicy chili sauce that adds a kick to the sauce. You can find it in the Asian foods section of most supermarkets. Freshly squeezed lime juice is essential for that bright, zesty flavor, so make sure to pick up a couple of limes.

Ingredients For Fish Taco Sauce Recipe
Mayonnaise: Provides a creamy base for the sauce.
Sour cream: Adds tanginess and smooth texture.
Lime juice: Freshly squeezed for a zesty kick.
Garlic powder: Adds a subtle garlic flavor.
Cumin: Brings a warm, earthy note.
Sriracha: Adds heat and a touch of sweetness.
Salt: Enhances all the flavors.
Technique Tip for This Recipe
When preparing the sauce, ensure that the lime juice is freshly squeezed to enhance the flavor. Using bottled lime juice can result in a less vibrant taste. Additionally, for a smoother consistency, consider using a whisk rather than a spoon to combine the mayonnaise and sour cream. This will help to fully integrate the ingredients and create a more cohesive sauce. If you prefer a spicier kick, gradually add more sriracha until the desired heat level is achieved.

How To Store / Freeze This Sauce
To keep your fish taco sauce fresh and flavorful, store it in an airtight container. A glass jar with a tight-fitting lid works wonders for preserving the taste and texture.
Place the container in the refrigerator. The sauce will stay fresh for up to one week. Always give it a quick stir before using, as some separation may occur.
If you want to prepare the sauce ahead of time or have leftovers, freezing is an option. Pour the sauce into a freezer-safe container, leaving a bit of space at the top to allow for expansion.
Label the container with the date to keep track of its freshness. The sauce can be frozen for up to three months.
When you're ready to use the frozen sauce, transfer it to the refrigerator to thaw overnight. For a quicker thaw, place the container in a bowl of cold water.
After thawing, whisk the sauce to restore its creamy consistency. If it appears too thick, add a splash of lime juice or a bit of sour cream to achieve the desired texture.
Avoid refreezing the sauce once it has been thawed, as this can affect the quality and flavor.
Always use a clean spoon or utensil when scooping out the sauce to prevent contamination and extend its shelf life.
How To Reheat Leftovers
Gently warm the fish taco sauce in a small saucepan over low heat, stirring frequently to ensure it doesn't separate or curdle. This method preserves the creamy texture and melds the flavors beautifully.
If you're in a rush, microwave the sauce in a microwave-safe bowl. Heat it in short bursts of 10-15 seconds, stirring in between to maintain an even consistency and prevent overheating.
For a more controlled reheating, use a double boiler. Place the sauce in a heatproof bowl over a pot of simmering water. Stir continuously until the sauce is warmed through. This gentle method ensures the sauce remains smooth and creamy.
If you prefer a cold sauce, simply remove it from the refrigerator 15-20 minutes before serving. This allows the sauce to come to room temperature, enhancing its flavors without any risk of separation.
