Orange tree is da bomb! I like it when I do pork, and like pecan - a little goes a long way. I know folks who will use it in their fireplace after a big tree dies – the wood is hard, and dense. It adds a nice flavor, more like an oak than anything else…
Trees are unfortunately dying due to a bacteria called "greening", or from a small weevil that digs through the roots. Out here on Kennedy Space Center there are acres and acres of groves that are untended - it costs more to maintain and harvest the fruit than it was worth. All the trees are just about dead - or reverting back to the wild orange root stock (think sour orange juice for Cuban pork roast).
I keep a bucket of orange chunks to throw in the UDS, with some oak…..
