These deliciously tangy Sweet and Sour Prawns are a tasty combination of tempura-battered wok-fried shrimp, vegetables, and pineapple coated in my homemade sweet and sour sauce! It's the perfect better-than-takeout Chinese food entree to make at home any night of the week!
In a medium-size mixing bowl, whisk the egg whites until light and foamy. Add the cornstarch and continue whisking until all of the cornstarch has dissolved and you have a smooth batter.
Heat a wok, large skillet, frying pan, or Dutch oven to medium-high heat with enough cooking oil to fry the shrimp. The oil should reach 350 degrees F (175 degrees C) when ready to fry your battered shrimp.
Coat your peeled and deveined shrimp into the batter using a heat-safe slotted spoon or fork. Let the excess batter drip off of the shrimp before placing them into your heated oil.
Fry the battered shrimp for 4-5 minutes, or until a light golden brown. Remove the cooked shrimp from your cooking oil and transfer to a paper towel-lined plate to drain off excess oil. Cook the shrimp in batches, if needed, until all of your shrimp are done.
Clean out debris from your oil and leave about 2 tablespoons of your cooking oil in the wok or skillet to stir fry your vegetables. Return the wok to medium-high heat and add your cut vegetables. Stir fry until tender, about 2-3 minutes.
Pour the sweet and sour sauce over your wok fried vegetables and stir to thoroughly coat the cut veggies. Add the shrimp back to the wok or skillet and stir to coat. Cook until the sauce is shimmering and the shrimp and sauce are heated through.
Remove from heat and serve immediately. Serve over steamed or fried rice, garnish with sesame seeds and chopped green onion if desired.
