Make the sauce, by mixing the chicken stock, oyster sauce, potato starch and sesame oil together in a small bowl.
½ cup low-sodium chicken stock, 2 teaspoons oyster sauce, 1 ½ teaspoons potato starch, ½ teaspoon toasted sesame oil
Heat a large skillet or wok over medium high heat until until very hot. Add the oil and then immediately add the cashews. Stir-fry until the cashews are a deep golden brown and then transfer them to a bowl, leaving as much oil in the pan as you can.
1 ½ tablespoons vegetable oil, 75 grams raw cashew nuts
Add garlic and ginger and give them a swirl in the oil, and then add the marinated chicken in a single layer. Let this fry undisturbed until the chicken is browned on one side.
Start stir-frying the chicken until cooked on all sides (it doesn't need to be cooked all the way through at this point).
Add the vegetables and continue stir-frying until they're cooked through.
60 grams baby corn
Give the sauce a mix to incorporate the settled potato starch and then pour it over the cashew chicken. It's done when the sauce comes to a boil and thickens. Plate and garnish with the scallions.
