We are in love with this fish taco sauce. If you have a fish taco obsession like we do then you know that a great fish taco sauce is an absolute must when making your own homemade fish tacos. This fish taco sauce is a blend of sour cream and avocado with cilantro, lime juice, chili powder, chipotle chili powder, and cumin. It's so good! Best of all it's super easy to make and goes great on more than just tacos. But it's an absolute must for fish taco lovers.
