Trim most/all the visible fat, then coat with LOTS of Kosher salt, a few cloves of minced garlic, some rosemary, black pepper, and some finely diced onion. Like, rub the whole bloody rack down with it. It should resemble a salt lick with chunks of garlic and onion in it. Leave it for an hour like this.
The salt draws a lot of the water out of the meat without "salting" it per se. It penetrates deeply into the protein as the water is displaced with salt, which breaks it down and vastly changes the texture of the meat.
After an hour passes, rinse the meat. Yes, really. With a gentle tap of cold water, rinse all the salt and other items off the meat. Pat it dry with paper towel. It's now ready to cook - here's where I throw on some steak spice and more minced garlic and diced onions. Throw them on low heat on the top rack of the BBQ until they start getting a bit of char around the edges, then flip 'em. Probably looking at 30-45 minutes total depending on the size of your cut. Don't overcook or they'll taste like flavored hockey pucks.
