G,
“Because according to their minhag you can’t wet matza in the first 7 days of pesach.”
The mainstream minhag i think is to be machmir not to eat it but you can still keep the mixing. I think it gets cooked before shabbos …
See below link that many have the minhag to allow children to eat Gebroks.
