'Szechuan' is often used as a catch-all term in British Chinese restaurants to indicate a bright red, slightly spicy sauce, and this recipe includes all those delicious sweet, sour and spicy flavours with an extra touch of fragrance from our MA LA BLEND! Here we're using king prawns (marinated with cornflour and baking soda for ultimate juiciness!) but you can substitute diced chicken or even firm tofu if you prefer.
