Store in a cold place.The day of:• Soak the burlap bags in water.• Heat the flat-top until it’s smoking hot.• Dump the oysters on top of the flat-top and cover with wet burlap bags to steam them and keep all the wonderful oyster juices.• When the oysters just begin to open, they’re done.• Remove the oysters and enjoy with some melted butter and Crystal Hot Sauce.Pro tip:Pour beer on the flat-top when steaming the oysters to add more flavor, Vetter says. If you don’t have the right kind of grill, use a a turkey fryer with a steam basket — just a little water to the pot and bring it to a boil. Put the oysters in the seam basket and cover until they begin opening.
