Yeah, but I think translating "the salsa" to "la salsa" it kind of pointless. Or the "sauce" translation should be used from time to time. This is not a big problem, just sayin. :D
This shouldn't really translate in English to "the salsa" as it refers to a very specific kind of sauce, and all sauces are called salsas in Spanish.
