Waitrose sell canned pumpkin - it's made by Libby's (called 'solid pack' - no spices added). Can't remember the exact price. Not cheap but worth it for occasional use. I have not seen it anywhere else - don't know about Sainsburys.. Thanks to helpful recommendations on this forum I always keep a can in the cupboard (along with the Chappie!) and have found it really helps with upset tums. As others have said, once opened you can freeze the rest in ice cube trays & then put in bags for later use.
