I am a bit of a scavenger. I have mulberry and redbud from my property. Maple and Cherry from around my neighborhood.
Mulberry - Goes well with pork, mild/med flavor. Grows all over my property, so I have a good supply of it.
Mesquite - I use mostly on chicken, sometimes pork on the weber kettle.
Silver Maple - a recent find that works great as a general purpose. I really like working with it.
Plum - haven't done much with it...not wild about it
Black Cherry - I love this stuff on pork and chicken.
Apple - I have some store bought stuff as a gift. It doesn't have a whole lot of flavor, IMO. I think it is just the wood though.
I have some redbud seasoning. I think it is close to being ready. trimmings are thumb sized and are already starting to split due to drying. Next spring I'll have to check out the brush along one property line. I think I have a small line of dogwood growing...might be smoke-able.
Started with a Weber. Stepped up to a UDS. Pepper fanatic.
