I’m pretty sure I figured out what it takes to end up with the best sauce ever.
Not only should you simmer your sauce as long as possible, but its also crucial to have a substantial bone* involved somehow. A nice, big bone gives you so much flavor.** I’m not kidding.
Today my goal was to find the biggest, cheapest bone*** at the grocery store and see how it impacted my sauce.
In addition to the bones from the pork chops, I also lucked out with a thick and meaty bone**** from a beef shin. Never in my life did I think I would cook a beef shin but, again, I was all about the bone.*****
Just try and tell me you could resist this bone:******

I’m going to ignore every single one of those asterisks and just say yes, you are correct about what gives the sauce good flavor.
