What
Hank Hill sells to
Texans. You see,
charcoal doesn't give a
clean-burning flame and that can affect the taste of your food.
Propane is also more
economical and
cooks more evenly than
charcoal. If you use charcoal--or even mention it--around
Hank Hill, you're going to get a
lecture.
It also helps, I assume, that Texas is a big petroleum state and manufactures quite a bit of propane which is sold by the big oil companies, so it's a Texan's duty to use it. I guess mesquite is okay too, but best if you throw mesquite chips over a propane grill for flavor (actually, I believe the best way to do this is to put moistened mesquite chips in a foil pouch which you lay on the lava rocks in your propane grill so they don't just burn, but smoke the food nicely).
