If you're into sous vide, this is an interesting product. The Sansaire Steak Aging Sauce is specially formulated to take a sous vide steak and make it taste like it's an expensive, dry-aged cut from a swanky steakhouse. Essentially, you toss the sauce in the sous vide bag and cook the steak like normal, then sear it on high. The sugars from the sauce caramelize into a beautiful crust on the outside, completing the steak.
The sauce has a high concentration of glutamic acid (see: MSG), as well as fish sauce to achieve this dry-aged feat.
