Sous vide – literally under vacuum –<\/em> is the packaging of ingredients in a vacuum-sealed bag then cooking them in a water bath at a teutonically precise temperature. Alex Renton wrote a great Guardian WOM piece<\/a> explaining the benefits: food cooks totally evenly, without high heat damaging flavours. Long cooking breaks down toughness leaving meats incredibly tender, and the bag prevents any flavours escaping. There is just one little problem. Or rather 500 to 1,000 problems plus VAT<\/a> \u2013 the cost of a temperature controlled water bath and vacuum sealer.<\/p>\n
But does sous vide cookery have to be expensive? A US movement, popularised by David Chang\u2019s Momofuku Cookbook<\/a> and its steak-under-a-hot-tap recipe (UK publication in October), is dedicated to improvising sous vide techniques. Known as ghetto sous vide, fans use ziplock bags, cheap thermometers and warm water to cook meat, fish and vegetables. I wanted to try this myself \u2013 hey, what could possibly go wrong? The equipment was simple: a digital probe thermometer<\/a> cost \u00a312 and I found zip seal bags in a drawer. Marky Market<\/a> provided some top-grade onglet and my stock pot acted as makeshift bath. The method too was simple: portion the meat, pop each portion in a bag, squeeze out the air and seal the bag. Squeezing out all the air was tricky (but important as air is a poorer conductor of heat than water so would cause uneven cooking) but partially submerging the bag in water then sealing the top helped.<\/p>\n
$\"\"$ <\/a>The bagged meat was submerged in warm water to cook – a degree warmer than the desired temperature of the meat when cooked. Onglet likes to be rare, so my water temperature was 52\u00b0C (water from the hot tap, topped up with the kettle, but accurately measured with the thermometer). The bagged beef stayed in the water until it had an internal temperature of 51\u00b0C which took 45 minutes. Anytime the water dipped below 52\u00b0C (3 or 4 times) I added some more from the kettle \u2013 a low-temperature alarm on the thermometer made it easy to get on with something else rather than constantly monitoring.<\/p>\n
$\"\"$ <\/a><\/p>\n
Finally the steaks were removed from the bags, dried with a towel, seasoned, then seared in a hot, dry pan for a few seconds. Fresh from the bath the outside of the meat had an unappetising colour – grey and insipid, in fact \u2013 but the searing gave a tasty brown colour and got some Maillard flavours going.<\/p>\n
The outcome? Delicious, especially with spuds, green beans and horseradish. The beef was rare \u2013 totally evenly cooked all the way through, with none of the toughness around the edges you get with grilled onglet. The short cooking meant the meat was not massively tenderised nor absent of sinew \u2013 that requires several hours in the bath \u2013 but it was notably better than a grilled steak. And the meat texture was totally different to a grilled steak: the characteristic grainyness of this cut remained loose after cooking, rather than tightening up \u2013 not necessarily good nor bad, but definitely different, and quite unusual. All things considered, this experiment was a big success.<\/p>\n
Would I do anything differently? Well, I\u2019d love to try to really tenderise the meat with long cooking \u2013 probably 8 to 12 hours. That said, longer cooking involves different issues in terms of food hygiene, so at this temperature you either need to cook relatively fast (as above) or for a really long time, but not for an in-between period like 2 or 3 hours. I expect I will try it, but I also suspect regular long cooking – and all the attendant fiddling with maintaining temperature – might be where that devilishly expensive\u00a0sous vide<\/em> equipment starts to look more attractive.<\/p>\n
Specialised sous vide equipment will eventually fall in price; the components are cheap and already used in plenty of kitchen appliances. When that happens I will definitely do some \u2018proper\u2019 sous vide. Until then you will find me playing with my ziplocks and thermometer.<\/p>\n
Have you tried ghetto sous vide? How did you get on? Would you try it?<\/em><\/p>\n

Safety note: This cooking method might sound like a recipe for botulism – but it is not as dodgy as it sounds. Plenty of sous vide cookery is totally safe, but a short cooking time like the one above does entail risks above normal steak-cooking methods.<\/p>\n
Don\u2019t try the method above unless you have educated yourself about the food safety risks and are willing to accept them. And if you do, remember, the meat can\u2019t be kept and reheated later. It goes without saying to use an excellent meat supplier, and not serve it to anyone old, young, pregnant, ill or with a compromised immune system. We can\u2019t go into a detailed sous vide safety discussion here, but this site<\/a> is a good place to start.<\/p>\n
