Start a few days before you plan to cook the roast and brine Your Roast first.
Remove the roast from the refrigerator and out of the brine about 1-2 hours (or more) before you plan to start searing the roast.
After the roast has been out for a bit and you are ready to cook, place the cast iron Dutch oven in the oven at 450°F (235°C) to preheat the cast iron.
Add oil to the outside of the roast.
When the Dutch oven is very hot (at or around 450°F (235°C)), place the preheated Dutch oven over a medium-high heat and let the pot start to show wisps of smoke.
Set the roast into the hot Dutch oven. Let the roast sear on each of its (imaginary) 6 sides for about 2-4 minutes (or a bit longer even) on each side.
Once all the sides of the roast are nice and seared, turn off the heat. Lift the roast out and place a trivet in the bottom of the Dutch oven and place the roast on that trivet.
Cover the seared and trivet-ed roast with the cast iron Dutch oven’s lid.
lace the covered pot into the preheated 200°F (95°C) to 225°F (105°C) oven.
After 3-6 hours or longer, pull the pot from the oven and have a fork at the ready. Insert the fork into the roast. If the fork enters the roast with little effort, the roast is ready.
The broth. Remove the trivet from the pot (if you used one). Place a colander over a heat-safe bowl sitting on a heat-safe surface. Strain the broth into that bowl. Then, pour the strained broth from the bowl into a heat-safe container like canning jars (always a great storage container). Refrigerate if you are planning to use at a later date.
