For "court-bouillon":
place the shallots,
wine, stock, bay leaf,
thyme, peppercorns,
coriander seeds, and 5 reserved
parsley stems in a saucepan over high heat. Bring to a boil, reduce heat, and simmer for 10 minutes. Add the snails and continue
cooking for another 5 minutes. Remove the snails and set aside, keep
warm. Strain the other solids from the court-bouillon.
