In a cast iron or stainless steel skillet, heat oil on high until it starts to smoke. Carefully sear the roast on all sides and both ends, for about 1 minute on each side.
Transfer the roast and its pan dripping to a large pot. Add the water and the remaining ingredients to the pot, cover and bring to a rapid boil for 10 minutes.
Reduce the temperature to low and cook for another 45 minutes or until the roast is tender.
Remove from pot and let roast rest for 10 minutes before serving.
