are fragrant, 2 minutes. Pour in the white wine
, bring to a simmer
, and cook until the liquid is almost completely absorbed, 5 minutes. Remove from the heat.
the remaining 4 tablespoons butter and add to the bread cubes along with the sausage, vegetables, turkey broth
, oyster liquor
and eggs. Season with the salt and black pepper and toss to coat.
Spread the dressing
mixture into the baking dish
and bake, covered with foil, 25 minutes. Remove the foil and continue baking uncovered until well browned and crusty, about 30 minutes longer.
