Christmas is coming up, and I generally help by opening the cranberry sauce:
I generally open the can on one end -- the bottom, which is not raised -- with a can opener. When I flip the can over, it doesn't slide out because of the vacuum created.
I have tried going around the edge with a knife, from the open side, but then I cut into the cylinder of cranberry sauce, which is not neat. I've also considered opening the top as well, but because of its convex lip, there is no safe way to do so with a can opener.
What is a better way to break the vacuum?
