Sous vide

Sous vide doesn’t cook food—it holds it at the exact temperature where change happens, then outsources flavour to something else.

Sous vide is a controlled-temperature cooking method invented by Georges Pralus in 1974. It uses sealed pouches or jars in a precisely heated water bath for extended periods. It guarantees even doneness and moisture retention but requires finishing steps for colour and texture. Bruno Goussault refined it by integrating vacuum sealing with thermal precision.

    The foie gras fix

    Georges Pralus invented sous vide in 1974—not as a gentle technique, but as a way to stop foie gras from melting apart.

  2. 2:32
    Temperature, not time

    It works by holding food at one narrow temperature range for hours, so every millimetre hits the same point of change.

  3. 4:14
    What stays sealed stays sealed

    Vacuum sealing traps juices and aroma—but only inside the bag, never in the pan or on the plate.

  4. 5:51
    The engineer’s upgrade

    Bruno Goussault didn’t invent sous vide—he made it reproducible by marrying vacuum sealing with precise low-temperature control.

The written brief1 min read

What the dish is and where it came from

Sous vide is a French-named cooking method invented by Georges Pralus in 1974, using sealed pouches and precisely regulated water baths for long durations.

How it works, in terms someone would actually use

Food is sealed in a plastic pouch or glass jar and submerged in a water bath held at a precise, low temperature—55–60°C for red meat, 66–71°C for poultry—for one hour to several days.

What it gets right

It delivers even cooking, prevents overcooking the exterior while fully cooking the interior, and retains moisture and aroma by sealing food in plastic.

What it does not

It does not brown food. It does not concentrate flavour. It does not replace seasoning, resting, or finishing steps.

What it changed

It changed professional kitchens by replacing guesswork with thermal control: chefs no longer rely on touch or timing alone to judge doneness.

Who it is for, and who it is not

It is for cooks who prioritise consistency over speed or simplicity—and for professionals managing volume, timing, and quality across shifts. It is not for home cooks seeking quick, intuitive results.

Is it worth your time

It is worth your time only if you need repeatable, edge-to-edge doneness in proteins or want to hold food at serving temperature without drying it out.

Maillard reaction1912The Maillard reaction is a foundational food technique — not a dish. It is a temperature-dependent, non-enzymatic reaction between amino acids and reducing sugars that creates brown colour and complex flavour. First described in 1912, it underpins searing, roasting, baking and roasting across cuisines. It is precise, teachable, and actionable — but only if treated as chemistry, not folklore.

Tonkotsu ramenTonkotsu ramen is a pork-bone broth ramen from Kurume, Fukuoka Prefecture, Japan, invented in 1937 by Tokio Miyamoto. Its defining technique is prolonged boiling of pork bones to yield a cloudy, milky broth, and it features culturally distinctive noodle firmness options.

AdoboAdobo is a vinegar-based immersion method. It began in Iberia as preservation. In the Philippines, it is an indigenous technique using vinegar, soy or fish sauce, peppercorns, garlic and bay leaves. The earliest documented reference is from 1850.

Apple strudelApple strudel is a technique-first pastry rooted in Viennese tradition and empire-wide practice. Its authority lies in dough discipline — not apples, not spice, not history — but in the physical act of flogging, discarding, resting, and stretching until the layer disappears into readability. It demands time, tolerance for failure, and attention to elasticity. It offers no shortcuts. It rewards only precision.

Al pastor isn’t Mexican street food—it’s Lebanese technique remade with pineapple, achiote, and Puebla’s insistence on corn tortillas.
