It's time for The Baltimore Sun's annual holiday cookie contest. Send your best recipes to Kate Shatzkin, Food Editor, The Baltimore Sun, 501 N. Calvert St., Baltimore 21278; fax them to 410-783-2519; or e-mail them to email@example.com with "cookie contest" in the subject line. The deadline is Nov. 5. We will select the best to be published in early December. This year, we're offering an extra incentive - cookbook prizes for those whose recipes are chosen.
