Meanwhile, in a saucepan combine marmalade, orange juice, ginger, and hot pepper sauce. Heat and stir. Serve over flounder. Garnish with orange sections and chives, if desired.
Note******Flounder, with it's firm, white, finely textured flesh, may be cooked many ways. The tangy orange sauce gives zest to this mild-flavored fish.
