How to Make It
Steep the orange pekoe tea bags in the boiling water until the tea is very strong, about 8 minutes. Remove the tea bags and stir in the sugar, salt and cider vinegar until the sugar and salt are dissolved. Pour the tea into a large bowl, add the lemons and 2 quarts of ice water and let the tea cool completely. Add the pork roast; it should be entirely submerged in the brine. Cover the bowl with plastic wrap and refrigerate for 2 days.
Combine all of the ingredients in a small bowl. Remove the pork from the brine and pat dry. Set the roast, meaty side up, on a rack in a roasting pan and generously coat with the sweet tea rub. Let the roast stand at room temperature until it is no longer cold, about 1 hour.
Preheat the oven to 375°. Roast the pork in the lower third of the oven for about 1 hour and 10 minutes or until an instant-read thermometer inserted in the center of the roast registers 135°. Let the pork rest for 15 minutes. Carve the roast by cutting between the bones. Arrange the chops on a large platter and serve.
