01 - In a mixing bowl, combine rice flour and salt. Gradually add hot water, stirring until a soft, pliable dough forms. Cover with a damp cloth and set aside.
02 - In a saucepan over medium heat, combine grated coconut, mashed bananas, jaggery, cardamom powder, cashews, raisins, and a pinch of salt. Cook for 3–4 minutes, stirring, until the mixture thickens and the jaggery melts. Remove from heat and let cool.
03 - Divide the dough into 8 equal balls. Flatten each ball into a 4-inch circle on a piece of banana leaf or parchment paper, about 1/4-inch thick.
04 - Place 2 tablespoons of filling in the center of each circle. Fold over to create a half-moon shape and press the edges to seal. If using banana leaves, fold the leaf over the dough parcel.
05 - Heat a non-stick skillet over medium heat. Add coconut oil. Place the parcels (with or without leaves) seam-side down and cook for 2–3 minutes per side, until lightly golden and crisp at the edges. Remove leaves before serving, if used.
06 - Serve warm as a snack or dessert.
