To understand the limits – one of R Moshe’s students did not eat gebrochts. Got married. Explained his minhag to his wife (or so he thought). Came to the kitchen 2 days before Pesach and saw his wife cooking kneldlach … not clear, whether he fotrgot to tell her, or she did not pay attention. So, he asked R Moshe – what is the way to deal with this situation? How to tell his new wife that the kneldlach are gebrochts?
