The zesty, neon-orange, entirely unhealthful, creamy nacho cheese that comes with nachos when you order them at the movies, Canada's Wonderland, etc. etc. -- as far as I know it is branded as Mexicasa nacho cheese but I am sure there are other very very similar brands -- does anyone know how to acquire small quantities of this stuff? Any brand is OK.
Tostitos makes a "salsa con queso" which isn't really the same thing, and there are other processed cheese products (e.g. valveeta) which don't even come close.
I am willing to try any nacho cheese that comes in a can!
