The “Sous-Vide” way of cooking, as described in the recipe for Slow poached marinated pork belly (”sous vide”- style) with Mushroom Basmati rice, is a method in which you seal raw and marinated food in a food grade plastic bag and then cook it at a low temperature in a water bath. The food, and I am referring mainly to meat, i.e. tough cuts of meat, comes out beautifully succulent and incredibly tender after a few hours. If, as a home cook, you want to experiment with this method of cooking, remember it is not really necessary to invest in expensive equipment. You need a reliable oven, a good quality ovenproof dish with a lid (I use a cast iron saucepan) that is big enough to hold the whole piece of meat instead of a temperature controlled water bath, a vacuum packing machine and patience. Compared to other cooking methods, the food cannot dry out and the flavor intensifies because all the seasoning and juices stay in and around the food.
The basic steps I follow i.e. for cooking pork belly, is to neatly trim the meat, then marinate it in a mixture of spices and stock or wine for a few hours, preferably overnight. When ready, transfer the marinated meat with the marinade to a food grade plastic bag that will withstand the heat, and seal it in a vacuum packing machine. If you do not possess a vacuum packing machine, do not despair. Try to get all the air out of the pouch after you have added the meat, then tie a secure knot. Simple! Preheat the oven to the temperature according to the recipe — usually relatively low, then heat water in the ovenproof dish to the same temperature as you have set the oven. Carefully lower the sealed bag into the hot water and make sure the bag is totally covered with the water. A good idea is to put a heatproof plate on top before you secure the lid on. Place the dish in the oven and set your timer for the desired time. When the cooking time is up, carefully remove the bag from the hot water with tongs and place in a deep dish. Cut the bag open and let the meat and juices slide out of the bag into the dish. If the juice is too thin, pour it off into a saucepan and over high heat, reduce to the desired consistency. The sauce will have all the flavors of the marinade as well as the meat. And as a bonus you have gorgeous tender and succulent meat!
