Usable "ON" any type grill surface. This is Smok'n Spices Smok'n Cone. Just light like a candle and let the paper burn down starting the spice pellets (about 4-5 minutes) put the food on the grill and let the smoked spice flavor infuse with a great taste. We suggest trying on a cold grill and when the Smok'n Cone is done smoking (35-45 minutes later) start the grill and cook to safe temperature. This package has 1 of each Oregano Spice, Sage Spice and our Mediterranean Blend spice. Base shipping for Smok'n Spice items ONLY is... Flat rate shipping 1 item $6.00, 2-5 items $12.00, 6- 12 items $16.00. We will add to other orders to make shipping cheaper when possible!
