The signature aspect of this traditional Phillippine stew is its pleasing sourness, which comes from the addition of tamarind and lime juice.

Put rice into a bowl. Cover with cold water by 2"; stir until cloudy. Let rice drain in a sieve; return to bowl. Cover again with water by 2"; stir until cloudy. Measure out 5 cups rice water; set aside. Drain rice. Put rice, 2 1⁄2 cups clean water, and salt into a medium pot; bring to a boil over medium-high heat. Reduce heat to medium-low and simmer, covered, until cooked through, about 10 minutes. Remove from heat; let sit, covered, for 10 minutes. Fluff rice. Cover to keep warm.
Heat oil in a pot over medium heat. Add onions and cook until softened, 2–3 minutes. Stir in rice water, daikon, and tamarind extract; bring to a simmer over medium-high heat. Cook until daikon is tender, 8–10 minutes. Add shrimp, tomatoes, pepper, and bok choy and reduce heat to medium; simmer until shrimp are cooked, about 5 minutes more. Stir in lime and patis; season with salt. Serve with the rice.
