What are some ways to keep cheese dip like salsa con queso from hardening while being eaten?

Answer 1

Eat faster? Actually, if you consider that you've used heat to liquefy a material that is normally a soft solid, two approaches quickly come to mind; first, you can try to keep the heat on by serving in a heated container (a purist approach), or second, you can add a second method of liquification (usually the commercial approach) such as adding a light vegetable oil in the minimum necessary amount and blending well. The amount of oil added determines how well it stays pleasantly goopy. Too much oil... unpleasantly goopy. Even though water or milk might also work, usually the best resulting texture is less appealing than a botched oil infusion
