Went camping recently and due to time constraints treated to some marinated chicken and steak tips. The steak tips had some kind of cowboy marindate and I think the chicken was lemon and garlic. What gets me is, I've tried marinading meats at home in the past. It's been so long, I can't remember exactly what I did. But they never come out as juicy as the ones you buy at butcher shops or in this case at McKinnons Market. They are just so juicy, doesn't matter if you over cook them for a little bit, and they are just so tender and melt in your mouth. My kids loved it and were begging for more. Is there some trick to this? Does anyone have any really good marinade instructions? Or any ideas around this.
People often misunderstand the difference between a marinade, and a brine. Marinades contain acid, which caused the proteins on the meat surface to tighten up and act as a barrier to any of the marinade flavor from entering more than just the outer layer of the meat. The general rule for marinades is - 15 minutes is as good as 15 days.
A brine is a solution of water and salt, usually with other flavors added, but no acid, like vinegar or wine. As the amount of salt in the brine is greater than what is found in the meat tissue, and all things seek to be equal in nature, osmotic pressure forced the salt water into the meat tissue, with the other flavors in the brine, be it sugar, or herbs and spices. This is how corned beef is made, as sell as most commercial bacon and ham (though in the bacon and ham, the brine is injected into the meat and allowed to distribute itself over time). But the process takes time, in the case of corned beef, a couple of weeks at refrigerator temperature. The meat absorbs more water, and the other flavors of the brine.
Extra hers, spices, and sometimes sugar, are used to coat the outside of the meat, allowing those flavors to be absorbed as well. So you get meat that is somewhat tenderized, and hydrated by the salt water, and flavored by the herbs, spices, and salt.
You now have the basic idea of how to brine your own meats to make them as good, or maybe better than those you purchase already brined. Just remember, acids are in marinades, and marinades don't penetrate into the meat. Brines to penetrate.
