Ornamental trees are just as suited for smoking as the fruit bearing varieties. Pear wood is similar to apple. It has a nice smoke flavor and adds a hint of sweetness to your pork and poultry, yet mild enough for fish and other light flavored game birds.
They are very susceptible to storm damage and most of the limbs are small enough that they will not have to be split.
I got some bradford pear from a guy that lives across from our shop. I had it laying on the rack to dry and thought, why not, so I threw a couple of splits on Thanksgiving day. Man, does it burn hot. My smoker jumped from 275 to 350* in a matter of minutes. With this knowledge, I will probably use it for chunks instead of splits.
