Not salsa, dip maybe. 'Virginia White Sauce Isn't Your Average Salsa'

[Hotler]

'When you sit down at a Mexican restaurant in America, there's one thing you can for sure expect: A complimentary basket of tortilla chips served with a few cups of salsa. A cup of pico de gallo or salsa verde is typical, but if you go out for Mexican food in Virginia, you'll find a surprising companion to your tortilla chips: a cup of white sauce. White sauce doesn't resemble traditional salsa at all, nor does it contain any cheese despite being white. It's a salsa all of its own.'

I don't think you will find this in New Mexico.
