You can store any leftover dip in an airtight glass container in the fridge at 38°F for up to four days max. Don't freeze this dish because the extreme cold breaks down the delicate dairy emulsion. It'll leave the texture completely grainy and ruined once it thaws out. I like to press a piece of plastic wrap directly onto the surface before closing the lid so a hard skin won't form on top of the cheese. When you're ready for round two, reheat your leftovers in a preheated oven at 350°F for about 10 to 12 minutes. You just want the center warm and the cheese beautifully melted again. If the mixture looks a little stiff or dry, don't panic. Just stir in a tablespoon of heavy cream before heating because that restores the original glossy texture. Always give it a quick sniff test before diving in and watch for a sour odor or liquid separation since those are clear signs it has spoiled.
