May I ask a question?
How did this discussion morph from the poster’s question – a query asking how and if the tradition of eating non-gebrochts on Acharon shel Pesach can be worked out this year – to a wholesale discussion on the validity of the minhag of not eating gebrochts?
Have we really descended to the point where we cannot handle minhagim that are different from our own?
The minhag of not eating gebrochts is not a recent phenomenon, nor are its roots of disputed origin. Those who keep it are right to keep it and to safeguard it. Those who don’t, don’t. Why is this becoming such an issue?
As to those who ask, if one doesn’t eat gebrochts all week of Pesach, how can they do so on Acharon shel Pesach, the answer is this: Because it is a chumrah. And in order to show that it is a chumrah and not me’ikar hadin, in chutz la’Aretz it has become a tradition to davka eat gebrochts on acharon shel Pesach. In EY, there is no such minhag as all days of Yom Tov are d’oraisa.
