BUFFALO CRUNCH DONUT: Tim Horton's just released the "Buffalo Crunch" doughnut, which will be served exclusively at the New York State Fair. The yeast doughnut is dunked in buffalo sauce and crusted with crushed up chips. A decorative corn-chip strip is placed in the center and comes in mild and hot varieties — mild is "toned down" with Ranch dressing. The $2-dollar mash-up could be first of many crossover items between Burger King and Tim Horton's as a result of Tim Horton's impending sale. (Grub Street)
