John’s Mother’s Lemon Sauce with Lemon Slices

My friend, Bon Appétit column collaborator and cookbook author Marie Simmons, got this recipe from her mother-in-law, Mrs. Beatrice Simmons. Try it, instead of the lemon glaze, over Marie’s Rich Gingerbread with Candied Ginger and Lemon Glaze or on any gingerbread or steamed pudding.
