I don't inject anymore. Used quite a bit of doctor'd butter for awhile and don't like the timing restraints for competing using that product. As said brining will out perform most other methods.Look up Shake's Honey Brine and use as a guide. Many turkeys and yardbirds have benefitted in moisture and flavor. Butcher's and Kosmo's both have good products. When I make brines they always have some sweet pop, root beer, creme soda,sprite along with some rub and a form of vinegar. Balance and volume of salt, sugars and water will determine soak times. Stubb's has a decent marinade for a change of pace. My best one's are when there's a bunch of good stuff, herbs, pop and whatever sauce I'm going to use in the brine. Endless combinations, and most are great. Steve.
