Q. If one cannot get a pomegranate to use as a siman for Rosh Hashanah, can he use pomegranate juice instead and say the yehi ratzon?
A. Piskei Teshuvos (225: 16) quotes Shraga Meir's ruling that one does not recite Shecheyanu on the canned juices of fruits one has not yet consumed on that year, since they may be from previous years.
However, Horav Shlomo Miller’s Shlit’a opinion is that one can say the Yehi Ratzon - Sheirbu Zechyosenu Kerimon - also on the canned juices.
