Corn has a great deal of pectin, the carbohydrate glue that holds vegetables together. Pectin doesn’t break down until around 183°F / 84°C, so you need to cook at a minimum of that temperature for corn to tenderize at all. At this temperature, it takes about 30 minutes for corn to tenderize while still retaining a bright, fresh crunch. Leaving your corn in the bath longer is OK, so long as you don’t go much longer than 2 hours, after which is begins to get too soft and mealy.


NOTE: If adding aromatics to the bag, add them sparingly. A few sprigs of herbs or half a split dried chili should do.

Ingredients for 4

  • 4 ears of corn (optional - leave in husk, with both ends trimmed)

  • 2 tbsp / 28.35 g butter, plus more for serving

  • Kosher salt

  • Aromatics (optional - cilantro, scallions, garlic, dried chillies, etc., sparingly)

  • Step 2

    Place corn, butter, and aromatics inside 1 to 2 vacuum-seal bags and seal bags or 2-3 zipper locking bags. Add two extra seals on each end to ensure sticking.

  • Step 3

    Clip a heavy metal spoon or knife to the edge of each sous-vide bag with a heavy-duty binder clip to weigh the court down. Place in water bath and cook for 30 minutes.

      Open bags, (if cooked in-husk, remove corn from husks and discard), discard aromatics and serve corn, passing extra butter at the table.
