- Heat the oil in a skillet over moderate heat. Add the shrimp and sugar and stir for 1 minute. Add the garlic and shallot, stir 1 minute, and add the water, fish sauce and salt.
- Reduce the heat and cook until the shrimp are done and the pan is almost dry, about 1 minute or so. Transfer to a plate, garnish with the cilantro and serve immediately.
