Why It Works

  • Beef shins or oxtail fortify the stock with extra meatiness for a full-flavored beef jus.
  • Stirring blended shio koji into the jus right before serving seasons the sauce, and it gives it extra savory depth, with a hint of funkiness that echoes the flavor of dry-aged beef.

Ourkoji prime ribneeds a saucy companion, so we made a stovetop version ofKenji's red winejusand spiked it with blendedshio kojito amplify the savory beefiness of the sauce.

Transfer beef to a serving plate and tent with foil to keep warm or set aside for another use. Stir in shio koji and taste for seasoning, adjusting with salt and pepper if desired (jus shouldn't need additional salt). Keep warm, until ready to serve withkoji prime rib.

Notes

A good homemade beef stock is great here, but you can also use homemade brown or white chicken stock. If you buy store-bought stock, we recommend chicken, as most mass-market beef stock has a poor flavor (if you know a source for good quality store-bought beef stock, such as a local butcher, that would work too).
