  We present here a numerical study of a lattice model of a chiral liquid. The
low symmetry of the favoured local structure depresses the freezing point to
reveal an exotic liquid-liquid transition characterised by the appearance of an
extended chirality,prior to freezing. What mechanisms impede crystallisation in
liquids with low molecular symmetry ? The ordered liquid can be readily
supercooled to zero temperature, as the combination of critical slowing down
and competing crystal polymorphs results in a dramatically slow crystallisation
process.
