Combine the shallots, garlic, and Creole Seasoning in a small nonreactive saucepan and place over high heat and cook for 30 seconds. Watch carefully so it doesnít burn. Add the wine and bring to a boil. Add the crawfish, salt, and pepper and bring back to a boil.
Stir in the glaze and bring back to a boil. Reduce the heat and simmer, skimming off the fat and impurities several times for about 10 minutes. Turn up the heat to high, skim the remaining impurities from the top of the sauce, and cook for 1 to 2 minutes.
Whisk in the butter and continue to whisk until thoroughly incorporated, for about 30 seconds. Add the green onions and remove from the heat.
