1. Whisk the egg white incorrectly (too soft).
Suggested solution: Please check my whipped egg white (the meringue) in the video and see how it looks like when I stop whisking.
2. Over mix when combining egg yolk and egg white mixtures (deflate all the bubbles inside the batter so the batter turns watery).
Suggested solution: Please mix the batter using a flat spatula, do not use a whisk to mix. And fold the batter like the motions in the video (look like I knead the batter with the spatula), please do it gently.
3. The pancakes rise well inside the pan and deflate after baking. The reason is incorrect heat level or timing.
Suggested solution: do not open the lid too often during cooking, lower the heat and cook longer. But I think the heat level and timing in my video is low and long enough through multiple tests I did.
