Bucket, congrats on the win, and congrats on moving to the "next level" of our hobby addiction....discerning taste! Because the SI is a such a "clean" environment, you can really taste the differences in seasonings and wood smoke. I treat wood smoke flavor as any other spice; it needs to match the meat, and my own taste preferences. I'll give you my preferences, but they may not be yours! For example, Jason favors apple in just about every smoke...I hate the taste of apple smoke! Mixed, it's not bad, but I do not like it by itself. So, whatever you hear is subjective to your tastes, and you will need to find your own through experimentation!
If there was only one smoking wood in the world, what would mine be? ...Hickory, without a doubt. I grew up on hickory BBQ, and to me, it just smells, and tastes, like BBQ!
If I have choices:
Beef: I prefer hickory, mesquite, white oak (whiskey barrel), red oak. Beef is hearty, and can take the stronger smoke of hickory and mesquite better than others. I also like pecan on beef.
Pork: Cherry is my favorite. I often mix a little hickory and cherry, or just straight cherry. Great with pork! I also like peach, but not as much as cherry. Good ol' hickory is always a backup. Hickory/maple is good, too.
Poultry: Again, cherry is the hands-down favorite on poultry. Maybe a mix of hickory/cherry, but usually just cherry. I also like maple or ash on yard bird.
Anything cured? Hickory, or mesquite (beef jerky).
Again, these are only my choices! Everyone differs, so try some and give us your preferences!
