the heating process causes evaporation of the moisture content in the "atmposphere"

thus when the Greggs™️ Sausage Roll is subjected to the heating/cooling cycle the inevitable conclusion is a loss of mass. If you subjected a Greggs™️ Sausage Roll to the same experiment in Outer Space, outside of the atmospherically controlled confines a spacecraft, you'd end up with a sausage roll that nobody could hear.
