Preheat oven to 425 degrees (or 400 degrees convection).
Mix all of the ingredients in a large mixing bowl together. You want the mixture to be thick but spreadable. Start with 500 ml of water and add more if needed to get a thick but pourable batter. If you need a little more water, add it 1 tablespoon at a time.
Line an 11x17 baking pan (with sides) with parchment paper. Make sure the parchment paper covers the whole tray and even goes up on the sides a bit. Spread the Kimchi Pancakes mixture across the entire tray evenly.
Bake for 40 minutes. Take them out of the oven and cut them into portions with a knife, flip ech piece over with a mini spatula. Be careful! They will be VERY hot! Then, return the tray to the oven for another 15-30 minutes until they’ve reached the desired texture. You can increase the oven temperature by 25 degrees to make them crispier and drier. They should be a bit crispy on the outside and cooked but tender on the inside.
Serve warm with dipping sauce or once cooled, freeze them (with parchment paper between each square pancake) in an airtight container. These warm up great in the toaster oven (at 350 degrees), oven, or even in the microwave.
