Bubur Kacang Hijau (Mung Bean Coconut Porridge)
Split mung beans (the green hulled kind) soak optionally 4 hours (cuts cooking time in half but not essential). Beans simmer in water with knotted pandan leaves, sliced ginger and a pinch of salt for 35-45 minutes until soft and split. Palm sugar dissolves in; cooks another 5 minutes. To serve: ladle into bowls; pour thick warm coconut milk over the top. Optional toppings: a sprinkle of fried shallots, a spoon of toasted black sesame, or chunks of toasted sweet bread (the Surabaya street-cart way).
