Opening Cans on Shabbos

< Back

Dear Rabbi Simon,
What is your opinion about opening cans on Shabbos?

Dear Kalman,
This is a complex question, which I will answer succinctly on this occasion. In brief, I don’t favour it, in accordance with the view of Rav Moshe Feinstein (and others). For this reason we generally don’t buy cans of beer or soft drinks for use on Shabbos at Kesher. However when they occasionally appear for whatever the reason, I allow them to be used, as many authorities are lenient. In such a case, it is best to empty the contents into a glass rather than to drink from the can directly (this is for halakhic reasons, beyond considerations of etiquette).
The type of can requiring a can opener (rather than “pop-top”): best to puncture top and bottom of can simultaneously.
Kind regards
Rabbi Rashi Simon

Ask the Rabbi: Quinoa on Pesach
Dear Rabbi Simon,
Where do you stand on quinoa (and the kitniyot ban) for Pesach?
Many thanks,
Dear Tzippy,
In line with other American authorities, I am in favour of quinoa. Although I reject completely the voices (mostly from Israel) seeking to abolish the ban on kitniyot entirely, IMO we do not need to include in the prohibition pseudo-grains that were unknown in the Old World until modern times. Best to buy with a Pesach hechsher though, to be free of any possible wheat contamination.
Rabbi Rashi Simon
