Just wanted to report that I made a version of this (a takeoff on Woodie's Make Ahead Turkey Gravy) for our prime rib Christmas dinner and it was absolutely fabulous! I roasted about 6 pounds of beef shanks and marrow bones along with 2 large chopped onions, 3 chopped stalks of celery, 3 chopped carrots, kosher salt, pepper, and a drizzle of olive oil at 400 degrees for 1 1/4 hours, stirring a couple of times. I deglazed the roasting pan with a cup of dry white wine. All contents of the roasting pan then went into the stockpot along with 4 cups of boxed low-sodium beef broth and 4 cups of low-sodium chicken broth and 2 bay leaves. Simmered that for a full hour or longer, stirring occasionally. Strained it through a sieve, pressing juices through the solids and refrigerated overnight. Next day, took beef fat from top of stock (there was very little), supplemented with butter in a saucepan and whisked in flour to make a roux. Heated stock to steaming hot, then gradually incorporated it starting with small dribbles into the roux with continuous whisking. This produced a very dark, moderately thick, intensely flavored gravy. (I could have skipped the prime rib entirely and just eaten this gravy for dinner.) It was my DH's birthday and he requested mushrooms in the gravy so I sauteed a combination of sliced portobello, shiitake and oyster mushrooms in butter and then added them to the gravy. I am grateful to Woodie for making gravy a no-stress, make ahead, delicious accompaniment to special dinners.

Found it!! Make-Ahead Turkey Gravy Makes about 2 quarts For more flavor, after roasting the turkey you can skim the drippings from the pan and add them to the gravy just before serving. It's best to discard the strong-tasting liver before using the giblets. This recipe makes enough to accompany a large turkey and still have plenty for leftovers. 6 turkey drumsticks, thighs, or wings reserved turkey giblets reserved turkey neck 2 carrots , chopped coarse 1 head garlic , halved 2 ribs celery , chopped coarse 2 onions , chopped coarse Vegetable oil spray 10cups low-sodium chicken broth 2 cups dry white wine 12 sprigs fresh thyme 1/2 cup all-purpose flour Table salt and ground black pepper 1. Adjust oven rack to middle position and heat oven to 450 degrees. Place giblets, neck, drumsticks, carrots, celery, onions, and garlic in roasting pan, spray with vegetable oil, and toss well. Roast, stirring occasionally, until well browned, 1 to 1 1/2 hours. 2. Transfer contents of roasting pan to Dutch oven. Add broth, wine, and thyme and bring to boil over high heat. Reduce heat to low and simmer until reduced by half, about 1 1/2 hours. Pour through fine-mesh strainer into large container (discard solids), cover stock with plastic wrap, and refrigerate until fat congeals, at least 2 hours. 3. Using soup spoon, skim fat and reserve. Heat 1/2 cup fat in Dutch oven over medium-high heat until bubbling. Whisk in flour and cook, whisking constantly, until honey colored, about 2 minutes. Gradually whisk in stock, bring to boil, reduce heat to medium-low, and simmer until slightly thickened, about 10 minutes. Season with salt and pepper. (Gravy can be refrigerated for up to 3 days or frozen for up to 2 months.) Reheat gravy in saucepan over medium heat until bubbling.

"...The definition of gravy refers specifically to a sauce made from pan drippings of a roasted protein. If you are not roasting the protein first, where are the drippings? Roasting necks and wings is not gonna do it! IMO," I picked up our turkey Monday night and did all the misc shopping. They had big necks and wings. (usually gone by the week or two before thanksgiving). Decided to make another fresh stock. One wing, one neck. DH roasted with veg when he got home. Then into the mauslin. I got home close to midnight last night and did the finishing. Straining and chilling. 2 quarts of gorgeous stock for gravy and the stuffing/dressing. Roasted proteins make drippings. Necks and wings are proteins and they are huge.

So the gravy involved experimentation, yelling, throwing food out, and frenzied remaking. I had a little pork stock and a good amount of duck stock. I expected someone to bring some turkey drippings, and we had boxed chicken stock for an emergency. I thought it would be fun to make a few kinds of gravy. So I did something that made perfect sense to me. I put about 2 c of AP flour in a saucepan and browned it. It was fun, I got to do that rolling thing where you move the pan to get the contents to roll into a wave and thus mix. Okay, the kitchen got a little smoky but oh well. My idea, you see, was that I'd have a jar of this pre-browned flour on hand for future "instant" gravies and general thickening. Because sometimes you need a sauce thickened right away and don't have time to mix raw flour with a little of the liquid, whisk it smooth, add and cook until the floury taste is gone, and you don't want the texture of a cornstarch thickened sauce. Then I made the gravy for my low cooked deep fried pork cubes. I simply put the pork stock in a small saucepan, added butter and pork fat, then stirred in the pre-browned flour. It worked great: dissolved right away, no clumping, no further cooking of the flour needed, and easy to adjust the degree of thickness by adding a bit more pre-browned flour (let's call this PBF for short) because the thickness responded immediately. That was easy, I thought. Then SWMBO started, not yelling exactly, but loudly expressing her disappointment and astonishment that I had cooked the raw flour, which is Never Ever Done and Unheard Of. DD took a few minutes to comprehend what I had done, then joined in the vocalization of Great Dismay. Protesting, DD proceeded to make the duck stock with my PBF. And immediately claimed it was a disaster. I was busy frying confit duck breasts so I didn't see what she did. I think she may have used the PBF as if it was raw flour, starting the roux by cooking butter and flour. Maybe the PBF quickly became burned - since I didn't do any additional cooking of PBF during the actual gravy making, I am not sure how it would tolerate further cooking. I just don't know. Anyway she said the texture was gritty and the taste was burned, and that all the duck gravy had to be thrown out. Throwing out a pint of duck stock is not something that makes DD happy. She said so. In the end, she started all over with the Normal Sane Roux Method You Dummy and made gravy with the turkey drippings and chicken stock, and it was fine. The pork bites drizzled with gravy turned out to be very popular. So there. And I have a jar of PBF that I need to hide or label as something else, lest SWMBO or DD find it and throw it out.
