In a medium saucepan coated lightly with oil over medium-high heat, saute shallots, garlic and lemongrass until soft, about 2 minutes. Add cranberries and saute another 2 minutes. Season with kosher salt and freshly ground black pepper to taste.
Deglaze with wine, reduce by 75%. Add chicken stock and reduce by 50%. Stir in lemon juice and sugar and whisk in the butter. Check for flavor and season, if necessary.
