I would really prefer an answer from someone who has worked in an American-based Mexican restaurant (simply meaning Americanized). I don't want one that has any sort of tomato sauce mixed in it. The kind I'm trying to make is made from all white cheese(s), & as such is colored white. I always assumed is was one kind of cheese with some milk or cream added to make it creamier so it doesn't bulk up when it cools a little, but I don't know the recipe. Some spice would be nice too, but if the recipe doesn't call for anything I'll just experiment with some jalapenos.
