Why You’ll Love This Recipe

This white sauce is a game-changer for fish tacos for several reasons. First, it has a perfect balance of creaminess and tang thanks to the combination of mayonnaise and sour cream or Greek yogurt.

Use it as a dipping sauce, drizzle it over grilled or fried fish, or even as a creamy salad dressing when you want a zesty twist. It takes just minutes to prepare, uses simple ingredients you probably already have, and can be customized to suit your spice preference or dietary needs.

Once you make this sauce, it will become your go-to condiment not just for fish tacos but for many Mexican-inspired dishes. It’s a simple culinary upgrade that makes a big difference!

Ingredients

• 1/2 cup mayonnaise (use full-fat for best creaminess)
• 1/4 cup sour cream or Greek yogurt for a lighter option
• 1 tablespoon fresh lime juice (about half a lime)
• 1 teaspoon white vinegar (apple cider vinegar works too)
• 1/2 teaspoon granulated sugar (balances acidity)
• 1/2 teaspoon garlic powder (or 1 small garlic clove, minced)
• 1/4 teaspoon onion powder
• 1/4 teaspoon cayenne pepper (adjust to taste)
• 1/4 teaspoon salt (or to taste)
• 2 tablespoons milk (to thin out the sauce as needed)

Equipment

• Mixing bowl (medium size)
• Whisk or fork for mixing
• Measuring spoons and cups
• Juicer or reamer for lime juice (optional)
• Storage container or jar with lid for refrigerating

Instructions

1. Combine the base ingredients: In your mixing bowl, add the mayonnaise, sour cream (or Greek yogurt), lime juice, and white vinegar. These form the creamy, tangy foundation of your white sauce.
2. Add dry seasonings: Sprinkle in the granulated sugar, garlic powder, onion powder, cayenne pepper, and salt. These add layers of flavor, with the cayenne providing a subtle kick.
3. Whisk until smooth: Use your whisk or fork to blend all ingredients thoroughly until the sauce is uniform and creamy without lumps.
4. Adjust consistency: Slowly stir in milk, one tablespoon at a time, until the sauce reaches a pourable, drizzly consistency. It should be thick enough to coat a taco but thin enough to drizzle easily.
5. Taste and tweak: Give your sauce a taste. Add more lime juice if you want more tang, extra cayenne for heat, or a pinch more salt as needed.
6. Chill before serving: Cover the bowl or transfer the sauce to a container with a lid. Refrigerate for at least 30 minutes to allow flavors to meld beautifully.
7. Serve: Drizzle generously over your fish tacos or use as a dip. Enjoy!

Tips & Variations

Pro tip: For a dairy-free version, substitute mayonnaise with vegan mayo and use coconut yogurt or a plant-based sour cream alternative. Adjust lime juice and seasonings to your taste.

– Make it spicy: Add a dash of chipotle powder or hot sauce for smoky heat.

– Herbaceous twist: Mix in finely chopped fresh cilantro or chives for a fresh herbal note.

– Garlic lover’s version: Use fresh minced garlic instead of garlic powder for punchier flavor.

– Thicker dip: Skip the milk and use the sauce as a thicker dip for crispy fish sticks or vegetables.
