This is what we just had for dinner. It’s not a great photo but tells the story of how last Sunday’s tri-tip and potatoes got turned into something “new.” My husband and I don’t eat a ton of meat so what we cook actually gets used up in many other meals during the course of a week.
Tonight it was a matter of eating up the roast, which we’d simply rubbed with lots of kosher salt, pepper, and dried summer savory, seared it stove top and popped it in the oven at 425 for 15 minutes per pound for medium or medium-rare (aim for 125-135F and rest for 10 minutes). You can also rub soy sauce or fish sauce on the roast along with pepper and garlic to marvelous effect. As we were getting things ready for dinner, Rory said, “I wish there was some gravy.”
That’s how this little impromptu sauce started. I remembered a conversation I’d had with chef Douglas Keane of Cyrus in Healdsburg about the virtues of combining miso and mustard – something he’d picked up from a renowned chef in Kyoto. Years ago, I made a simple red wine sauce with lots of shallot and whole grain mustard from a Martha Stewart recipe. There was a tub of dashi stock in the fridge to serve as my stealth umami infusion. With all of that in mind, I made a quick savory-sweet-tart sauce for the beef. As with past posts on repurposing leftovers, this one is also about how I cook on the fly.
