Place the lamb chops in the fridge and marinate for 24 hours.
Place the water into your water bath, attach your Sous Vide precision cooker to the water bath. Using your app, set the temperature to 56.5c/133.7f for 2 hours.
Place the lid on the water bath and wait until it reaches its desired temperature.
Once at temperature using your tongs, place the sealed lamb chops bags into the water bath and place the lid back on.
