IsometimesAgree – thanks for the link to the article – it’s a very good summary of the issue. One minor point re: one of the examples they bring, though – they mention that if one used Shmita onions to make soup, the entire soup is Kedushas Shviis. The problem is that it’s pretty much impossible now to have a situation where Shmita vegetables are Mutar at all (the Shita of the Chazon Ish on Yevul Nochri notwithstanding), since Shmita vegetables, even if they grow on their own, are Assur miderabanan under the Gzeira of Sfichin! A better example would have been something made with Shmita fruit…
