Pakhala is a traditional Indian dish with authentic regional flavors and aromatic spicing. This beloved preparation is a family favorite that showcases the incredible diversity of Indian cuisine.
Spread the cooked rice out in a wide bowl to cool completely to room temperature for about 20 minutes.
Add 5 cups of water and half a cup of plain yogurt to the cooled rice; stir together until the rice breaks up and the mixture looks milky.
Sprinkle the salt evenly over the top and mix until well dissolved.
Heat oil in a small pan over medium heat; when hot, add mustard seeds and let them sputter for 10-15 seconds.
Add sliced green chilies, grated ginger, and curry leaves to the hot oil; sauté for 30-40 seconds until fragrant, then immediately pour this tempering over the rice-water mixture.
Stir thoroughly to incorporate the tempering, then sprinkle the chopped cilantro over the top.
Cover and refrigerate for at least 1 hour for flavors to meld, or chill overnight for enhanced sourness before serving.
