Mix wheat flour, a pinch of salt, a little Ajinomoto (optional), bean sprouts, sliced onion, and one egg in a bowl until well combined. Stir in five tablespoons of Jeeny’s Sambal Udang Kering and a splash of water until the batter is smooth and pourable. Fold in the prawns, then fry spoonfuls in hot oil until golden brown. Drain and serve immediately for a crispy, flavorful snack.
