I think the best thing I can do is tell you what I do and why so you can make informed choices. There are dozens of different ways to approach this. If it's a 14 week old bird, it'll like be tender what ever you do. If you put it in the freezer last night it won't be fully frozen at this point. Once fully frozen it will take about 3 days to thaw in the fridge.
Why brine? Brining has two purposes: 1) put flavor into the meat and 2) help breakdown the meat to make it more tender. His brine recipe does neither from my view. My brine uses citric acid to help tenderize the meat and herbs and aromatics to add flavor. I brine a turkey that is mostly, if not fully thawed as the brining process doesn't start until the bird is thawed. And I brine for 12-24 hours.
I start with a large (12 qt) pot I'll add a couple rings of olive oil to the bottom.
Every thing is rough chopped
4 onions just chopped into quarters, don't waste time removing skins.
1 bunch celery
4 carrots
6 bunches of garlic
1 sweet apple
1 sour apple
1 orange
2 lemons
4 limes
A handful of cracked or whole black pepper.
3lbs kosher salt
3lbs local honey
Stock
Poultry herbs (parsley, oregano, thyme, and sage)
Sage
Add the first four ingredients, sprinkle with a little salt and saute for 10-15 minutes, then add the next six ingredients and continue to saute another couple minutes. Add the salt and honey, stir well and add 4 quarts of stock and bring to a boil. Make sure the salt is dissolved and turn fire off. Add 1 bunch parsley, two bunches of sage, two sprigs of rosemary and a half bunch of thyme. also a couple sprigs of oregano (or a couple packs of poultry herbs and a pack of sage). Let the fresh herbs steep in the hot water 15-20 minutes.
I use
this type of cooler I add a small bag of ice to the bottom, then pour the hot brine into the cooler and stir. Cool the brine to room temp. Submerge the turkey into the brine and top off with ice. Let rest 12-24 hours. When you bring it out of the brine rinse well inside and out.
I'll get into cooking in my next post.
