Drain the pineapple and collect the juice. Cut rings into smaller pieces. Clean and wash the bean sprouts. Drain the bamboo shoots. Clean and wash the paksoi and cut into strips except for the stalk.
Peel the garlic and press it through a garlic press, carve the chilli lengthwise, remove the seeds and chop. Heat the oil in a wok and sauté. Fry the garlic and prawns for about 3 minutes. Season with salt and cayenne pepper and set aside.
Fry the chilli and pineapple pieces for about 3 minutes, too, and put them aside. Add the soy and bamboo shoots and paksoi to the wok. Add sauce and stir in prepared ingredients. Season to taste with salt, cayenne pepper and 4-5 tablespoons of pineapple juice.
Scented rice tastes good with it.
