Q. This year when the last day of Pesach is Shabbos and eating Kneidlach on that day is a very important tradition in our family. Since we don’t eat Gebrochts (Matza dipped in water or matza flour baked, as Kneidlach are), the whole Yom Tov and we have to cook them on Friday, do we have to invite someone that does eat Gebrochts then so we can cook them on Yom Tov for him?
A. On a similar question (1675) we wrote: “Poskim permit preparing the kneidlach on Erev Shabbos, the Seventh Day of Pesach, even for those who strictly refrain from having matza touch water or liquids during Pesach. Although, it cannot be eaten on that same day for them, many others are lenient and eat matza shruya all Pesach, and it would be fit for them.
This applies only if an Eiruv Tavshilin was done. (Machazik Brocho 467: 6, Haelef Lecha Shlomo 343, Mikroei Kodesh 2: 60, Nitei Gavriel 3: 19 et. al.)
