Recipe: Mexican Restaurant-Style White Sauce

I have been looking for this too. This is what I came across by googling spanish white sauce. I will try it as well.

"Recently I went on quite a mission to find a recipe for the infamous white sauce served at many Mexican restaurants. This is not a gravy or a cream, or even a cheese sauce, but rather a side-by-side served with tortilla chips before the big meal."

1 quart Hellman's Mayonnaise
1/2 tsp. garlic salt
4 ounces of grated bleu cheese (Treasure Cave Crumbled Gorgonzola is what you really want - it comes in a container with the perfect amount needed.)
1/4 cup dill pickle relish (not sweet)
1/4 cup finely chopped salad olives with pimentos
2/3 cup dry milk powder
2 cups of water
