Cooking condensed milk in pressure cooker?
My Cuban wife wants to cook a can of sweetened condensed milk in the pressure cooker for an hour. She's quite certain that the can should be unopened. She says that her mother cooks this often, and even called her mother to verify that the can should be cooked unopened.
Does the pressure cooker prevent the can from exploding? I suppose that if the pressure in the pressure cooker increased proportionate to the pressure inside the can, it wouldn't explode. Until you released the pressure from the pressure cooker.
Should I let my wife go ahead and cook this?
