The closest to Beef Villa's Italian beef I have found.
Why does dry-rubbing a rump roast before introducing liquid matter so much for flavor penetration? Searing meat at 450 degrees Fahrenheit triggers the Maillard reaction, forming surface amino-acid complexes that hold herb compounds during subsequent braising. Applying half the spice blend directly to the raw protein allows garlic powder and onion powder to bond with surface fats, while the remaining seasonings dissolve into the pan juices later.
Using dried herbs instead of fresh ones is chemically advantageous here; dried basil, oregano, and Italian seasoning lack water content, meaning they release essential oils slowly into the simmering broth over one to two hours rather than scorching in the oven. Crushed red pepper flakes and fennel seeds infuse the liquid with capsaicin and anethole, cutting through the heavy fat content of the beef bouillon base.
Chilling the initial pan juices until the fat solidifies permits clean removal of excess grease before the final simmer. Slicing the beef paper-thin after a twenty-minute cooling rest ensures the muscle fibers hold together under the knife instead of shredding into fragments.
