What exactly is tetrazzini? In order to use up leftovers, I made a variation on what I thought its main constituent parts to be—turkey or chicken, pasta, cream sauce, peas, and mushrooms—only to look it up after the fact and learn that there is no actual consensus on what exactly it consists of. (Also, that the dish was named after the opera singer at left.) So my variation was as good as any—not to mention being a quick and hearty reworking of leftovers to the tune of $3 in new ingredients.
Backstory: Monday, I made roast chicken, which I had marinated in Brooklyn Lager topped off with some chicken stock, rubbed under the skin with Old Bay and garlic powder, and stuffed with a sliced clementine and a head of garlic for flavor infusion. While the chicken rested, I made pan gravy with the drippings and more chicken stock plus a little of that beer brew. Also, I made frozen peas and Stove Top. (As regular readers may recall, the Rob loves his Stove Top.) This was a very satisfying meal, and also I made a very flavorful stock out of the chicken carcass.
Fast-forward to this evening (is this an action-packed saga or what?!): I purchased a bunch of parsley, an 8-oz. package of mushrooms, and a box of linguine—which frankly I should have already had on hand, but for once I was out of dried pasta.
