In a small saucepan, combine rice, lentils and water. Cover and bring to a boil, then reduce to a simmer and cook until tender and water has evaporated, about 25 minutes. Fluff and transfer to a large bowl to cool. In a skillet, temper dressing by heating vegetable oil over medium heat. Add black caraway seeds and cook for about 1 minute. Seeds should sputter a bit. Remove from heat. Add tamarind paste and water, stirring to combine. Pour dressing over rice and fold to mix thoroughly. Fold in coconut and cilantro. Add lime juice and salt to taste. Transfer to a serving bowl. Serve warm or at room temperature. Enjoy!
