Very well prepared. You'll get c.5 large ribs and c. 5-6 medium from the rack, depending on the weight. Very little trimming needed before applying the rub. The large ribs will probably benefit for low-and-slow foil wrapped oven cooking before applying more rub and finishing on a a medium-low heat BBQ. Then add the glaze to finish. I allow 4-5 hours overall. The chill-pack was excellent.
