Andy,
I think this came from Parker, but here it is:

1 gal water
1 gal Apple Juice
1.5 cups Kosher Salt
20 cloves garlic (minced)
2 tablespoons BLACK Pepper
1/3 cup Brown Sugar
1/4 cup Worcestershire Sauce

Brine over night, rinse, dry, butter under skin, toss on the bbq covered with cheese cloth soaked w/butter. Remover cheese cloth at mid point.

220 max temp

Yank it off when the breast hit 160.

I did this for 36 men in BC a few years back and they keep wantin more!
