About This Fish Taco Sauce
The signature of a memorable fish taco is a delicious, creamy sauce that complements the mild flavor and crisp texture of white fish. This sauce is inspired by the beloved coastal taco stands of Baja California and Southern California, where simple ingredients are transformed into vibrant toppings. The classic recipe centers around a handful of kitchen staples: mayonnaise, sour cream, lime juice, and spices. In minutes, you’ll craft a sauce with just the right balance of tang, heat, and richness—perfect for drizzling, dipping, or spreading.
