For Filling: 1. Heat oil in large saute pan (medium heat), add mustard seeds and ginger.
2. Once seeds begin to pop, add onions and cook for 4 minutes.
3. Add cauliflower, cabbage, chiles, cashews, peas, turmeric, lemon juice and salt to taste. Once cooked, about 6 to 7 minutes, cool and fold in cooked potatoes.
4. When cooled, add cilantro and reserve.
For Dough: 1. Mix flour and salt. Add toasted cumin seeds and butter or ghee. Mix in ice water and form like pastry dough, adding additional water as needed. Cool in refrigerator for 1/2 hour.
2. Roll out dough, about same thickness as pie dough (1/8-inch thick). Cut into circles, 3-inch to 3 1/4-inch in diameter (using a ring or a glass). Egg wash edges of dough and fill with a generous teaspoon of vegetable mixture. Fold over in a half-moon shape and crimp edges with a fork.
3. Deep-fry in 350 F. oil or bake in 400 F. oven for 23 to 25 minutes. Serve with mint or coconut chutney.
*For a denser consistency, substitute potato flour.
