Elite sausage gravy involves frying the sausage (spicy of course), adding the flour (make sure you cook down at least a minute to get rid of any floury taste), then starting the gravy with some chicken broth. Let simmer, then add heavy cream or half and half (no measly milk). Then season for taste (namely some salt, pepper, cayenne and perhaps a little thyme) and simmer before pouring over biscuits of your choice.
