Heat oil in a pan, add the cumin seeds and fry for 30 seconds. Then, add the chopped fennel, ginger, and Thai chili. Saute for 4-5 minutes until fennel is soft.
Mash the cooked Java beans to a coarse texture with a potato masher.
Then add the mashed lava beans to the fennel mixture followed by fennel powder, cayenne, salt, and mashed potatoes. Cook for about 5-6 minutes until the mixture is dry. Remove from flame, transfer to a bowl. Add chili flakes (optional) and cilantro, and mix.
Divide the dough and the filling into 9 equal portions.
Flatten each dough portion to a 5-inch disc. Place a portion of the filling and gather ends to seal. Dust with flour and roll it into a 8-9 in. circle. Repeat with the remaining dough portions.
