Chile Con Queso

Instructions

1. Melt the butter in a medium saucepan over medium heat. Add the flour and cook, whisking constantly, for about 1 minute. Add the half & half and whisk until evenly combined. Bring to a simmer and cook until thickened, a few minutes. Turn the heat down to low and gradually add the grated cheese, whisking and letting it melt as you go, until all of the cheese is incorporated. Stir in the salt, chili powder, cayenne pepper, cumin, garlic powder, onion powder, diced tomatoes and green chilies, and cilantro (if using). The mixture may seem a bit thick at first, but it will thin out slightly as the tomatoes and peppers release their juices. Taste and adjust seasoning if necessary; for more heat, add more cayenne pepper. If the dip seems too thick, you can thin it out with a bit more half & half or some milk. Transfer the queso to a bowl and serve warm with tortilla chips. If the dip cools while you're serving it, you can reheat it in the microwave; just stop and stir at short intervals so it reheats evenly.
