Sous Vide Guide

How Sous Vide Works

Sous vide (French 'under vacuum'): cook food in a sealed bag in a precisely temperature-controlled water bath. Key principle: food cannot exceed the water temperature. Conventional cooking: food surface 200°C+, centre 50°C — gradient. Sous vide: entire food reaches set temperature precisely. Advantages: impossible to overcook (within reason). Edge-to-edge even doneness. Tougher cuts become tender with long cook times. Convenient: cook ahead, finish later. Equipment: immersion circulator (Anova,

Temperature Selection

Steak doneness by temperature: 50°C: blue. 54°C: rare. 57°C: medium rare. 60°C: medium. 66°C: medium well. 71°C+: well done. Sous vide at this exact temperature: perfectly cooked from edge to edge. No grey overcooked band around the perimeter as with grilling. Chicken safety: NHS recommends 75°C internal temperature for traditional cooking — but this assumes brief exposure. At 60°C held for 35+ minutes (or 56°C for 90+ min): equivalent pasteurisation. The Time-Temperature combination is what kil

Time Selection

Two factors: heat through time (time for centre to reach set temperature). Texture time (how long held at temperature affects texture). Heat-through times: 2cm steak from fridge: 30-45 minutes. 4cm steak: 1.5-2 hours. Whole chicken breast: 1-1.5 hours. Texture/tenderisation: tough cuts (chuck steak, brisket) become tender with extended cook times. Brisket: 24-72 hours at 60°C. Chuck steak: 24-48 hours. Pork shoulder: 24-36 hours at 74°C. Chicken: tender at 1.5 hours, dry after 4-6 hours at typic

Finishing — The Critical Step

Sous vide alone produces pale meat — no Maillard reaction. ALWAYS finish to develop crust and flavour. Steak: pat dry, season, sear in screaming-hot cast iron pan with oil, butter, garlic, thyme. 30-60 seconds per side. Or torch with blowtorch. Pork belly: chill after sous vide, then crisp skin in hot oven or under grill (broiler) for crackling. Chicken skin: crisp in pan after cooking. Skin must be DRY before finishing. Fish: brief sear (10-20 seconds skin side) to crisp skin. Don't overcook in
