  Using computer simulations, we establish that the structure of a supercooled
binary atomic liquid mixture consists of common neighbour structures similar to
those found in the equilibrium crystal phase, a Laves structure. Despite the
large accumulation of crystal-like structure, we establish that the supercooled
liquid represents a true metastable liquid and that liquid can borrow crystal
structure without being destabilized. We consider whether this feature might be
the origin of all instances of liquids of a strongly favoured local structure.
