You know how it is you’re a bit lazy so you just chuck that pack of sausages into the freezer all together. Then you only want to eat two but the damn things have frozen together, you can’t defrost them separately and refreeze them so you’re going to have to break them apart whilst frozen. Cue stabbing with knives, cut fingers, bashing of sausages against the work top and if you’re lucky you’ll end up with a couple of edible sausages rather than some messed up sausage meat.
