In a small mixing bowl, combine the kosher salt, granulated garlic, and black pepper to create a spice blend. Sprinkle all of the spice blend over the meat.
Toss the seasoned pork lightly in the all-purpose flour. The meat should have a light dusting of flour. Shake off any excess to prevent it from scorching in the oil when you sear the meat.
Heat the vegetable oil in a 10 or 12-quart stockpot over medium-high heat. When the oil in the pot begins to shimmer, add a handful of the seasoned meat to the pot. Avoid crowding the pot, or the meat won't caramelize properly, leave some space around each piece of meat.
Sear the meat for 3-4 minutes, turning it to sear each side well. Use a slotted spoon to remove the meat from the pot to a bowl or dish, then add the next batch of meat. Continue searing the meat in batches like this until they're all browned, and browned bits remaining on the bottom of the pot.
Sauté the Aromatics, then Deglaze the Pot with the Beer
If no oil is visible on bottom of your pot, add another tablespoon to it. Once the oil is hot, add the onion, celery, carrots, and garlic to the pot. Sauté the veggies over medium-high heat, frequently stirring with a wooden spoon, for 3-4 minutes, or until they are glossy and just starting to take on a golden brown color.
Pour the Guinness into the pot. Be careful because it will steam quite a bit. Once all of the beer has been added to the pot, use the spoon to scrape that browned bits (fond) from the bottom of the pot.
Return the Pork to the Pot, Along with the Veggies, then Simmer
Once the fond has been scraped from the bottom of the pot, add the beef stock to the pot.Next, return the seared pork to the pot. Bring the liquid in the pot up to a gentle boil.
After the stock has come to a boil, add the butternut squash, potato, sweet potato, boniato, and bay leaves to the pot. Bring this mixture back up to a boil, frequently stirring to keep anything from sticking to the bottom of the pot.
Once the stew is boiling, cover the pot and reduce the heat to low.Simmer the stew for 35-45 minutes, or until the potatoes are fork-tender, stirring occasionally.
Add the Herbs at the Right Time, then Serve
If you are using dried herbs, stir them into the stew towards the last 10 minutes of cooking time. Once the potatoes are tender, remove the stew from the heat and serve.Fresh herbs can be stirred in just before serving or right before you turn off the stove.
Ladle the stew into soup bowls and serve with warm, crusty bread or on its own.
