What is the white sauce on fish tacos made of?

Fish tacos are a popular dish, especially in coastal regions of the United States and Latin America. The white sauce that is often served on these tacos is a creamy, tangy topping that adds a delicious flavor to the tacos.

The white sauce is typically made of mayonnaise and/or sour cream, mixed with lime juice, garlic, and cilantro for a zesty flavor. Some recipes also call for yogurt, cream cheese, or other dairy products. The ingredients are blended together until a smooth, creamy sauce is achieved. The sauce can be thinned out with a bit of water or milk, if desired.

The white sauce is a great way to add a cool and creamy texture to the tacos, along with a zesty flavor that complements the fish and other ingredients. It's also easy to make, so it's a great topping to add to fish tacos. For a variation, some recipes call for adding chili powder or cayenne pepper to the sauce for a bit of heat.
