Heat the wok and pour in the peanut oil. Fry the prawns in it for 2 minutes per side and fish out.
Sauté the ginger, garlic, chilli and paprika over a medium heat for 2 minutes. Deglaze with the balsamic vinegar. Add the chicken and lemon juice, stir-fry for 1 minute, season with salt and pepper, cook over low heat for 5 minutes.
Just before the end of cooking, stir in the prawns, season with a pinch of sugar and fold in the basil strips.
