Some more BBQ tips, since I love to grill so much
Keep that grill clean! No matter what. I like to clean it anytime I take somthing off the grill. Invest in a nice grill brush, one with replaceable heads. Charcoal Companion sells some nice ones.
Oil it down. As Poly said olive oil is perfect for this. Before you put anything on the grill lubricate it with some olive oil. This will keep things from sticking and give a nice surface to grill on. A peice of fat will work here also.
For a nice cross hatch look on the meat cook it for 2 mins on one side, flip, 2 mins the other side, flip again but rotate the cut 45. Do this to the other side once again an you got some quality lookin meat!
