Link to original recipe:
I use mine for "fake" burnt ends. They turn out great!
Poke holes with knife, season and soak in worcestershire sauce over night.
Smoke for 7-8 hours at 225
Cut into cubes
Roll in Sauce and Re-Season lightly
Cook for 2 hours at 240 (roll about every 30 minutes)
I have finished them in my home oven as well on a cookie sheet using the broiler (roll about every 5 minutes). This only takes 30 minutes or so... depends on how much caramelization you like.
To answer your question... at 7-8 hours I'm down 45-55%
