With the keilim mikvaos closed and us only having enough bechers for the Seder, what cup can we use for Kos shel Eliyahu – year round glasses primarily cold (require kashering?), plastic, etc? Thank you!
The Ashkenazi minhag is to do hagala on glass cup even if they were only used for cold, alternatively you can fill the cup up with water and leave the water inside it for 24 hours, spill out the water and repeat three times. However if you have any other Pesach glasses or even a plastic cup, you can use that for Kos shel Eliyahu.
Although this year there most probably will be difficulties at the seder, but I”YH this should be the last seder in golus
