Place the shrimp and starch in a medium-sized bowl and toss to combine.
1 ½ lb medium-sized shelled shrimp, ¼ cup cornstarch
Make the sauce next. In another bowl or large measuring cup, combine the tapioca starch with a small splash of the stock. Mix well then add all the remaining sauce ingredients.
Heat the oil in a large frying pan over medium-high heat. Add the shrimp to the pan in a single layer. Work in 2 batches, if needed. Cook the shrimp for 1 minute then flip it over and cook for 1 minute more.
2 tablespoons cooking oil
Pour the sauce into the pan and stir until it has thickened, about 1 minute. Stir in the cashews and serve with some sesame seeds and minced cilantro over the top.
¾ cup cashews, Sesame seeds and minced cilantro
Notes
If you have raw cashews on hand, you can toast them for 7-8 minutes in a 350-degree Fahrenheit oven. Remove them once they are golden and smell fragrant.
