Request block-style American cheese from your grocer’s deli counter for optimal texture. Although American cheese is recommended, Velveeta can be substituted if necessary. Wear kitchen gloves while handling jalapeños to safeguard your skin and eyes, and wash hands thoroughly afterward. The smoker’s temperature may be increased to 250°F if needed. For extended serving, maintain the queso’s warmth in a slow cooker or chafing dish, stirring occasionally and thinning with extra evaporated milk if it thickens excessively.
