I've made this exact recipe several times in the past, and it's fantastic. It's exactly like the queso dip served at all the local Mexican restaurants in my neck of the woods. We prefer to call it "crack cheese", as it can become rather addictive when served with warm tortilla chips. Even better, pour it over your burrito or fried chimichanga.
I made this a few months ago, as soon as I found the recipe on Pinterest, from the same site you reference. It is like the cheese dip my Mexican restaurant USED to make, until they went cheapo. Only melted cheese now, which would make me sad, except I've got their old recipe! When I prepared it yesterday, after a few minutes, DH asked me to put it away, so as not to eat it all! I think that says a LOT! Nice to have it here for easy reference - Thanks for posting this great recipe, Random Rachel!
