that's sort of how turkey breast cold cuts are made.
i'd always wondered how they could call those big, round-ish lumps of turkey "all white breast meat". no turkey breast i ever saw looked that big or round. when trimming a turkey, the breast is always more of a smaller football shape.
then i saw a show on how they make turkey cold cuts. raw turkey breasts are injected all over with some kind of enzyme that causes proteins to break down. then the breasts are put in tumblers to help the gooey broken down proteins to ooze out.
when sufficiently gooey, three to four breasts plus small, leftover bits are put into a semi-round, plastic shell, vacu-sealed, and steam cooked sort of like a high temp sous vide.
the gooey proteins glue the breasts together forming in the shape of the shell. the shape of turkey "breast" you see at the butcher.
they're peeled out of the shell, covered in various flavouring sprays (brown roast, honey, cracked pepper etc), and then the flavour quickly baked on.
i was put off at first but i love a good turkey sandwich now and then, so i gave in.
like buzz mentioned, at least it's not raw surfaces in the middle of a steak as depicted in the video, nor are selling scraps as the real deal, so i can live with it.
but raw steak glued together? no way jose!
