Years and years ago, I came across a recipe for San Diego fish tacos and fish taco sauce. It was really good. The sauce included in the recipe, however, burned a little hole in my brain.

That sauce … omg, so good. Forget salsa. Forget sour cream. Forget tartar sauce. You’ll never want anything on your fish tacos except this sauce, ever again.

No doubt my fading memory and stubborn inability to leave well enough alone has inserted itself on the original recipe. But that’s the beauty of a spice-heavy concoction: You can tweak the sauce seasonings to your own tastes.

So, don’t worry if you’re missing an ingredient from the list, and you’re in the middle of a taco craving emergency. It will all be a-okay!

What makes this fish taco sauce so tasty? It’s the unique combination of herbs and spices, including cumin, coriander, smoky chipotle chili powder, dill, and oregano.

Plus, it features the perfect hit of heat: not enough to say, whoooaa, tongue on fire! But just enough to be all like, hello, I’m alive, and it’s great to be eating tacos!

Here’s what Pinterest users are saying about this awesome Fish Taco Sauce:

It was SO good! My family loved it! ~ Kerry

This sauce is so good, I’ll eat it on everything. ~ Marly

Absolutely awesome, was even better than the sauce we got with our fish tacos in Mexico ~ Werner

The Secret Ingredient for Fish Taco Sauce

And now, here it is: capers. Capers have a unique tang that’s a cross between bitter and briny.

But when you combine them with other assertive flavors, like the spice blend above, it somehow turbo-charges everything else, while hanging out quietly in the background.

Use non-pareil capers if you can find them (they’re smaller with a more delicate flavor), and mince them well with a knife, or smash them with a fork.

Fresh cilantro leaves with a sliced lime

And then there’s my all-around favorite flavor combo. Lime and cilantro (above) are so natural together, it would not have surprised me one bit to find them growing on the same plant, had I not grown cilantro myself without producing a single lime (I knew better, of course, but was still unreasonably disappointed). There’s plenty of both of these summery flavors in my fish taco sauce!

Coriander, by the way, is the seed produced by the cilantro plant. Redundant, both leaf and seed sharing a spot in the same recipe? No, sirreee. Ground coriander tastes nothing like its leafy parent.

Gently aromatic and somehow citrusy, it adds a bright flavor to mexican dishes, and is an especially delicious companion to cumin.

So, for you unlucky ducks where cilantro leaves tastes like soap, do not fear the ground coriander!

How to make fish taco sauce

This white sauce is easily whipped up with just a whisk – no special equipment required:

  • Whisk together mayo and sour cream until smooth.
  • Thin with a little lime juice until the sauce wants to drip from the whisk.
  • Add the spices and mix thoroughly.
  • Let rest in the fridge for at least an hour, to let all the flavors blend into tasty goodness.

Spoon the sauce over your fish tacos — my favorites are made with grilled flaky white fish, like cod or halibut, but shrimp is scrumptious, too. For an authentic San Diego experience, try them battered and fried. Delish!

Ingredients

  • 1/2 cup reduced fat sour cream (Greek yogurt is delicious as a substitute if you're not a fan of sour cream)
  • 1/2 cup reduced fat mayonnaise (you can use full fat, but, the spices are so delicious, you won't miss that particular flavor contribution)
  • 1 lime , cut in half
  • 1/2 teaspoon cumin
  • 1/2 teaspoon ground coriander
  • 1/2 teaspoon dried dill weed
  • 1/2 teaspoon dried oregano
  • 1/4 teaspoon ground chipotle chili powder
  • 1/2 teaspoon capers , minced
  • 1 hot pepper of your choice , seeded and minced (jalapeno is delicious, as are the cherry bomb poppers I used in this batch).
  • 1 tablespoon fresh cilantro , chopped

Instructions

  • In a small bowl, whisk the sour cream and mayonnaise until well blended.
  • Squeeze the juice from one lime half into the fish taco sauce mixture, then whisk thoroughly. You'll want the consistency of a pourable, creamy salad dressing. If still too thick, add more lime juice from the other half. If too runny, add sour cream.
  • Add all of the spices, whisking to mix thoroughly. Add the capers, minced pepper and cilantro, and whisk thoroughly.
  • Cover the bowl with wrap and refrigerate the fish taco for at least one hour — the longer the better.
  • Serve chilled. Spoon white sauce over fish tacos, or add into taco salads or rice bowls.

Seriously the best sauce ever. I just use all chili powder. I substituted the cumin and coriander for chili powder. And I use alot more cilantro it's my favorite herb.

Just tried this fish taco sauce and used it on our fish tacos and it’s so amazing. What a great thing on a snowy night.

I haven't tried this sauce recipe yet and it seems with all the wonder flavors added together that it will be fantastic. I just have one question, if I omit the mayonnaise will it take away from the recipe? There isn't anyone in my family that is fond of mayo, so I thought I would just use greek or plain yogurt.

Over the years, I’ve made this recipe with just about everything white that you can, lol. It’s absolutely fine with all Greek (that’s my personal preference). Mayo adds a tiny touch of non-sugary sweetness, but I don’t mourn it when it’s not there. A little blip of honey can replace the sweetness, but I don’t think you’ll need it. Hope you decide to try it!

For the pepper do you use fresh pepper such as jalapeño , or do you use pickled peppers?....just curious.

I use fresh! I think a little bit of pickled peppers would be delish, but I think they would shift the flavor of the sauce in tartar sauce territory.

I’ve used this recipe at least a half dozen times now. Awesome stuff. I buy a 5-6 lb swordfish tenderloin, cut it in about 1/2 lb steaks and freeze it in two packs. Every other pack is fish tacos and this sauce is the star
