How do I make my own matzo meal cake flour?
Matzo cake meal is simply matzo meal that has been ground more finely. If you can’t find matzo cake meal in your local grocery store, just take regular matzo meal and pulse it a few times in the blender or food processor until it reaches the consistency of a finely ground powder. I think, from memory, that potato starch is added when making desserts, so it would depend on what you were using it for. There are many kosher recipes available online that will tell you if potato starch is needed.
