Considering their extensive use of all kinds of chiles, Latinos really know their hot sauces. Since I stock my fridge with several kinds of hot sauce (each one has a different use!), when it comes to Mexican cuisine, I have one brand I can't get enough of: Valentina salsa picante. This slightly smoky, thick, and spicy sauce is wonderful on everything from eggs to tacos.
How about you? What's your favorite kind of Mexican hot sauce? Tapatio? Cholula?
