Dear Rabbi Simon
I have a box of kosher for Passover Manischewitz gluten free matzo style squares at home. On the box, it says it is not a replacement for seder matzo. It was one of the post-Pesach bargains I picked up this year. Its listed ingredients are potato flour, potato starch, potato flakes, tapioca starch, palm oil, vinegar, egg yolk, dates honey and salt. It is not made from one of the five grains so I assume that one cannot recite hamotzi over it and thus cannot be used as a substitute for bread for hamotzi. Is that correct? What blessing does one say over this product? Does one say the “ha’adamah” or the “shehakol” blessing over it?
Thank you for your practical question. You are correct that it cannot be used in place of challah (or matzah) for lechem mishneh, for example. The correct blessing is שהכל נהיה בדברו.
