Pork ribs were all the rage during the past two decades. For a while, it seemed as if baby back ribs were on every other menu. Now, beef ribs are king again. They owe their newfound popularity in the greater Houston area largely to Ronnie Killen of Killen's Barbecue. These are not your grandpa's beef ribs, though. They sport a huge slab of meat on the bone. Just one of them is a full serving of beef. That's because Killen uses plate short ribs that come from the chest area of the cow, not the back. Other barbecue places have followed suit and are also offering plate ribs. So, in a way, Killen has made carnivores all over town happy. His own tender, juicy ribs sell out daily, so get there early if you want to try the best.
