  • Fryer
  • Cast iron pan
  • Sous Vide Immersion Circulator
  • Cooking Container


  • 500 grams potatoes peeled and cut into 1/2" batons
  • 1/2 cup water
  • 1/2 tbsp salt
  • 1/4 tsp sugar
  • 1/4 tsp baking soda
  • vegetable oil for frying


  • Stir together water, salt, sugar, and baking soda.
  • Put potatoes in a sous vide bag with the brine.
  • Cook for 15 minutes at 381.2°F.
  • Air-dry the potatoes.
  • Fry at 266°F for 7 minutes.
  • Drain and let cool.
  • Fry for a minute at 374°F.


  • Make sure to use enough oil so the temperature does not drop as you get the potatoes in, or, work in small batches.
  • No need to set-up a timer. You'll know they're ready when they float on top of the oil and develop a loose blistered-like exterior.
