Dear ChefSteps: A Request --
I can make incredible stock. I've made some fantastic demi glace in my time. I've taken the jus from several kilos of SV short ribs and turned it into an amazing sauce that would make a person want to slap their own mother.
But one thing I simply cannot do is replicate the low quality, super-salty, thin "au jus" dipping sauce that you get with any French dip or Chicago beef sandwich at any mediocre restaurant. I'm not talking about real "beef jus"; I'm talking about real 'Merican "au jus" -- the industrialized agriculture "off-the-shelf" version. But better and real and made from scratch. How have Sysco and Swanson and Arby's figured it out, but I -- a Stock Master -- have not?
No matter how mush salt, MSG, or Worcestershire I throw at the problem, it's just not the same. I think the answer may be to start with that thin, overpriced, garbage "stock" you find on the shelf at the grocery and doctor it up... but that solution makes me sad. That's how Sandra Lee would do it. And Sandra Lee is an enemy of quality.
At any rate, I want to make some epic roasts this holiday season. And epic roasts means epic leftover roast beef. And epic leftover roast beef needs jus! What to do?!
