Carrabba's Italian Grill's Lemon Butter Sauce

Directions

1. To clarify butter: Heat 1/2 stick butter over low heat. When melted, remove from heat and set aside for several min to allow the lowfat milk solids to settle to the bottom. Skim the clear (clarified) butter from the top and throw away sediment. (This can be done ahead.)
2. To make sauce: Heat clarified butter, add in onion and garlic and saute/fry till transparent. Add in lemon juice and white wine and season to taste with salt and pepper. Simmer 2 to 3 min to reduce liquid.
3. Remove from heat and swirl in cool butter till sauce is smooth and emulsified.
