I want to make some hummus, but on opening (two!) cans of garbanzo beans, where I was expecting to find them in liquid, instead they are suspended in a jelly-like mass. It's so thick that it won't come out even turning the can upside down - had to spoon it out. Both cans have probably been in the pantry +/- a year. It doesn't smell odd but am unsure if it's okay to eat. Please advise.
