If you want toffees of uniform shape, score the slab of toffee while it’s cooling to make it easier to break apart when hardened. Otherwise, break the toffee with a toffee hammer once it’s cooled.
On the other hand, I am as capable as the next guy to sit mindlessly munching on a box of factory made chips or curls or crackers. I don’t think, I definitely don’t savor, I just eat.
