Notes
If you're making it in large quantity, then put the roast in an instant pot in batches. Don't overfill the pot otherwise, the meat will not get tender as it should be.
You can adjust the spice level up a bit too.
Most people add vinegar too in the sauce. but it's up to you how much tarty flavor you want in your recipe.
Reserving it in the fridge after being cooked enhances its flavors!
