Nimbekai chitranna, or lemon peanut rice, is a specialty of South Karnataka made with lemon, coconut, peanuts, and cilantro.” Truly, though, there are numerous variations of chitranna. At its heart, it’s a rice dish that’s usually sour in nature and flavored with fried spices and curry leaves. The sour can come from many sources, not just lemon — lime, green mango, or tamarind are also used.
