Asymmetric reheating is a generic requirement for models of dark sectors with
light species, but its implementation is usually in tension with unique
phenomenologies otherwise possible in compelling theories containing dark
copies of the Standard Model. We present a simple module to implement
asymmetric reheating during a $mathbb{Z}_2$-breaking phase above some critical
temperature. This reinvigorates the possibility of an exactly degenerate mirror
sector and the striking phenomenology of composite particles oscillating into
their mirror counterparts.
