The cleanest wood for smoke flavor bar none. Mojobricks burn real slow and make cooking with wood simple and fun. Mojobricks minis are the smallest of the three sizes. One mini adds just the right amount of smoke flavor. Burn times vary but typically you have no need to refresh the wood for 45 min or more. Mojobricks hickory minis are especially good for mouth watering smoke flavor on beef, poultry, chicken, pork and wild game. What holds the compressed wood together, no glue or chemicals only an organic binder called lignin, it grows in the tree and binds the Mojobricks hardwood during the process.
