If you have leftover pancakes, or you just want to make them ahead of time, let them cool completely and wrap them tightly in stacks of 2. I like Glad Press 'n' Seal for a tight seal. Store them in the refrigerator for up to 3 days, or the freezer for up to 3 weeks. To refresh, let defrost at room temperature if frozen, sprinkle with water and place in the toaster oven at 250°F until warm.
