This video explains three reasons why fluffy pancakes don't rise and provides specific tips to avoid failure. Using one bag (150g) of Morinaga pancake mix as a baseline, it carefully compares and examines the three causes: the amount of milk, overmixing, and cooking time. It explains that too much milk results in poor rising, while too little makes them dry, but 90ml is optimal for good rising and a fluffy texture. It also explains that the best timing is to thoroughly whisk the egg first, avoid overmixing after adding the pancake mix, cool a preheated pan over medium heat with a damp cloth, and cook over low heat for about 3 minutes on one side and about 2.5 to 3 minutes on the other side. By understanding these points, anyone can easily make thick, fluffy pancakes.
