Because this recipe is made with real ingredients, it does harden as it cools a little faster than the cheese dips made with processed cheese products. However, you can keep it warm in a slow cooker after making or reheat as you’re enjoying it. It reheats beautifully! Add a bit of milk when reheating if necessary. You can also leave the initial dip a little thinner than you would want to eat since you know it will thicken as it cools as well.
