Step 1

Heat a sauce pan or small pot to medium heat. Add the butter and melt it.

Step 2

Stir in the flour and stir continuously for 2-3 minutes to form a roux.

Step 3

Stir in the milk and allow to simmer. It will bubble just a bit around the edges.

Step 4

Reduce the heat to low, then stir in the cheese a bit at a time. Continue stirring until it all melts through.

Step 5

Stir in the pickled jalapeno juice (and some of the pickled jalapenos, too, if you want!). Keep stirring until the nacho cheese sauce is nice and smooth.

Step 6

Taste and adjust for salt, then serve with tortilla chips!
