To prepare the Sous vide, you will first need to fill its container with water, then adjust the temperature to 149°F (65°C). Leave it to preheat.
Mix together in a separate bowl the soy sauce, sugar, rice vinegar, minced garlic, and oil.
In a zip-lock bag, put the chicken breast and mix in the teriyaki mixture thoroughly. Align the chicken pieces in one layer in the bag.
Now, for the ‘Water displacement’ technique, close the bag containing the chicken breasts completely except one corner to allow air to come out. Dip the bag in a water filler container, keeping the zip-line above the water surface. Close the zip-line completely.
Dip the bag completely in the Sous Vide container. Leave it to cook for 1 hour.
When the time is over, remove the chicken from the bag. With a paper towel, dry them well. Preserve the content of the bag.
Dump the content of the bag into a skillet on medium-high heat.
Pour a mix of cornstarch and water into the pan. Stir well to allow the sauce to thicken.
Put the chicken pieces into the pan after removing them from the flame, and mix them with the sauce to properly coat them.
