Using slotted spoon, remove onions from skillet.
- In same skillet set over medium heat, melt remaining butter. Cook garlic, stirring, for 30 to 60 seconds or until softened. Sprinkle with flour. Cook for 1 to 2 minutes or until smooth. While whisking, slowly pour in cream and milk; bring to a boil. Reduce heat to low. Cook, stirring occasionally, for 3 to 5 minutes or until slightly thickened. Stir in in chives, thyme, mustard powder, paprika, nutmeg, remaining salt and remaining pepper.
