Final answer:
Fish or shrimp tacos are commonly served with crema or a variant like chipotle crema, and a salsa such as salsa verde or pico de gallo for enhanced flavor and texture.
Step-by-step explanation:
Typically, the two sauces served on the side of fish or shrimp tacos are crema or a variant thereof, such as chipotle crema, and a type of salsa, like salsa verde or pico de gallo. These accompaniments are key in enhancing the flavors of the tacos.
Crema, a sauce similar to sour cream but thinner and often with added flavors, provides a creamy texture that balances the spices and the crispness of the taco shell or toppings. Salsa, on the other hand, offers a zesty or tangy component that complements the seafood. In some regions or restaurants, you may also encounter variations such as avocado-based sauces like guacamole or aioli-based sauces.
The choice of condiments may vary by personal preference, regional influences, or restaurant style. In Mexican cuisine, a lime wedge is also commonly served with tacos to add a fresh squeeze of acidity.
