Yes, cornmeal pancakes can be made in advance. These pancakes freeze beautifully, so they’re a great make-ahead recipe. Simply cook the pancakes as instructed, and let them cool. Then store them in an airtight container for up to 1 month in the freezer. Be sure to separate any layers with parchment paper to prevent sticking. When you’re ready to serve, thaw the pancakes in the fridge, then reheat them in a pan over medium-low heat to warm and re-crisp.
