A favorite technique of restaurant chefs, sous vide cooking is becoming popular in home kitchens as well. And no wonder – foods emerge with amazing flavor, texture and juiciness. The method calls for cooking food slowly in a low-temperature water bath inside vacuum-sealed bags. This professional thermal circulator offers precise temperature control and a pump that continuously circulates water to ensure even cooking.

  • Easy to use—simply set the thermal circulator, place the vacuum-sealed food in the water bath and leave it to cook.
  • Inside the airtight bags, foods cook in their own natural juices, guaranteeing tender, flavorful results every time.
  • Great for make-ahead meals, vacuum-sealed pouches can be stored in the refrigerator or freezer until you're ready to use them.
  • Sous vide cooking locks in food’s natural flavors, nutrients and moisture.
  • A favorite of professional chefs everywhere, this unit runs day and night in many top restaurant kitchens.
  • Setting it apart from standard sous vide machines, it features a powerful pump that actively circulates heated water throughout the pot to ensure uniform cooking temperatures.
  • Pump speed regulation allows this machine to circulate up to 8 gallons of water at a time.
  • The unit clamps securely to the side of any stockpot or large container.
  • Cooking temperatures adjust from 59°F to 212°F with the push of a button – and can be set to 1/10th of a degree.
  • Large LCD screen displays actual and desired temperatures (in Fahrenheit or Celsius), so you can monitor progress at a glance.
  • Made in USA.
  • A Williams Sonoma exclusive.

Milk Poached Halibut Flavored Rosemary

Set the Sous Vide Professional to 125°F (52°C), with the rear pump flow switch closed and the front flow switch set to fully open.

Season the halibut with salt.

Place the halibut in a vacuum bag and add the milk, rosemary and kaffir lime leaves.

Seal the bag to the desired vacuum (make sure the fillets are not overlapping); for delicate fish, 80% to 90% vacuum is desirable. This will ensure the flesh of the fish is not compressed under vacuum, compromising the integrity of the delicate muscle fibers.

Once the target temperature of 125°F (52°C) is reached, place the bag in the circulating water, making sure it is completely submerged. If necessary, place a small weight on the bag.

Cook the halibut to the desired doneness, 12 to 20 minutes.

Remove the bag from the circulating water and carefully remove the halibut from the bag. If a sear is desired, pat the halibut dry with paper towels and season with salt.

In a hot pan, warm olive oil or butter. Add the halibut and sear until a golden crust forms on both sides. The halibut may also be grilled, if desired. Serves 4.
