Melt 1 Tablespoon butter in same
skillet then add shallots and saute until tender, 2 minutes. Add wine,
chicken broth,
balsamic vinegar, and fresh cherries, if using, then simmer until sauce is reduced by nearly half, 3-4 minutes. If using frozen cherries, add now with
thyme then continue to reduce sauce until slightly thickened, 2-3 minutes, pressing down on cherries gently with the back of a wooden spoon.
