California Grill masters pride themselves in cooking tri-tip with oak wood. This takes a lot of time, and I don't have oak wood readily available. It's not cheap! When I found this recipe in an issue of Cook's Country Magazine (part of the Cook's Illustrated family) I knew I had to make this. Forget BBQ sauce... this is an amazing recipe! Cook's Illustrated adapted this recipe where you used wood chips, soaked in water. You grill the tri-tip, seasoned only with salt & pepper (the Santa Maria way) and-- towards the end-- you add the wet chips to the coals to give a smoky flavor to the meat. I'm telling you, if you love to eat red meat-- this is to die for! Seriously, it's worth trying.
