Cut tips off wings; reserve for stock. In small bowl, stir together garlic, mustard, paprika, thyme, sugar, cayenne, salt and black pepper; blend in lemon juice to make paste. Using pastry brush, brush paste over wings. Arrange wings, meaty side down, on lightly greased foil-lined baking sheets. Let stand for 30 minutes at room temperature. Bake in 475F oven for 15 minutes; turn wings over and bake for 15 to 20 minutes or until brown, crisp and no longer pink inside.
Peach Mustard Sauce: In saucepan, melt jam over low heat; stir in mustard, pimiento and vinegar. Serve separately for dipping.
