Pork Loin Roast, Sous Vide Method

Sous Vide Roast Pork Loin

Prepared according to the procedures recommended by son Ben. The dry rub is mine. 

about 1.5 lb pork loin
about 3 T vegetable oil

Dry Rub

2 T kosher salt
2 t granulated garlic
2 t fennel seed
1 t dry thyme
1 t peppercorns
1 t paprika
1 t sage
1 t dry rosemary

Process the above ingredients in a spice grinder about 20 seconds until fine, and store in an air-tight container. Lightly rinse the pork loin and dry thoroughly with paper towels. With a sharp knife cut away most of the fat cap. Rub all the surfaces with the spice mixture, using 1 tablespoon of dry rub per pound (15 ml per 450 g). Prepare a water bath fitted with a heating circulator set to 137 F (58 C). Put the meat in a twist-tie plastic bag and force the air out by the displacement method. The thin wall facilitates squeezing the air out. Tie a tight knot at the top of the bag taking care not to let air back in. Lower the bag into the water gently. Add hot tap water, if needed, to bring the level to the maximum permitted by the circulator. Cover the pot with plastic wrap to limit evaporation. Process for 4 hours. When the time is up, remove the roast from the bag and reserve the juice rendered during cooking. Dry the surface thoroughly. Heat a stainless skillet over medium high, add the oil, and then the roast. Brown it on all sides, turning with tongs. Pour the reserved drippings over the meat. Slice thinly and serve.
