Ingredients for 3

  • Step 1

    Set your Anova Sous Vide Precision Cooker to 80ºC / 176.0ºF

    In a bowl, whisk together eggs, chicken broth, water, and salt until thoroughly combined.

    Pour the egg mixture into 4 oz / quarter pint mason jars up to 1/4 inch below the top. Cover the jars with the lids and twist until just finger tight.

    • Finishing Steps - Sauce

    • Step 0

      Add about 1/2 tbsp of chopped scallions on the top of the eggs inside each jar. Place the jars in a splatter-safe place (I usually use the sink). Please note: it is important to do the following steps in order to avoid large splatters or potential burns.

    • Step 1

      Heat canola oil in small pan until it starts to smoke. Remove the pan from the heat and pour a bit of hot oil into each jar - about 1/2 tbsp each. Be careful, the scallions will sizzle, smoke, and splatter. If there is no sizzle, the oil is not hot enough.

    • Step 2

      Spoon 1/3 tbsp soy sauce into each jar. Wipe down the sides of the jars in case of any splatters and serve.
