Great TBS! Fuel for the cold smoke...lump, hickory and apple chips. Using the Smoke Daddy Butter before the smoke Everything turned out wonderful! I did a 2 1/2 hour smoke for everything. The eggs i eat the next day, some will be deviled, the butter smells incredible and will be wrapped back up for cooking later. The onions, well i'm not sure if they take on cold smoke but they are used for cooking all the time so i'll let you know!
