I really like pecan with beef. One day last summer I was getting ready to grill some chuck eyes for dinner when I discovered that I was out of charcoal. I didn't feel like making a trip to the store so filled a chimney up with pecan lumps and burnt them down to coals and grilled my steaks over them. By far one of the best tasting steaks I've ever eaten. I've used pecan on pork butts too and they came out good.
