Thick Batter Troubleshooting- As the batter sits, it will thicken. Ideally you'll want your chickpea egg batter to sit for 1-2 minutes before cooking. It should look similar to a pancake batter right before cooking. If you go to cook and its too thick, add 1-2 tablespoons of water to thin it out. A thick batter may lead to a dry egg.
