Alton Brown continues his culinary endurance test in “Alton’s Maniacal Baskets: Part 3.” The appetizer round opens with black radishes, tuna noodle casserole, pickle jelly beans, and lutefisk. Entrée piles on with BBQ cottage cheese salad, rack of elk, cauliflower leaves, and natto, forcing chefs to wrestle with bold, clashing flavors. Dessert brings a strange finish with musk stick marshmallow tart, frozen rhubarb, rock candy, and black limes.
