For an even smokier flavor, add a handful of wood chips to your grill or campfire. Adjust the amount of jalapeño to control the spice level. Feel free to substitute your favorite cheeses in this recipe. For a creamier consistency, add a splash of milk or half-and-half while melting the cheese. This queso can also be made in a slow cooker. Simply combine all ingredients and cook on low for 2-3 hours, stirring occasionally, until melted and bubbly.
