In a mixing bowl add all purpose flour, salt and oil; add water slowly while mixing and kneading to make firm, yet pliable dough.
Cover and set dough aside for at least 10 minutes.
Mix Kachori Filling ingredients together (gram flour, asafetida, salt, chili flakes, mango powder and oil). Set aside.
Knead dough for a minute and divide into 12 equal parts.
Roll dough ball into a 2-inch diameter circle and place 1 teaspoon of filling in the center. Seal by pulling the edges together to make a ball. Prepare all 12 kachories and let sit for 3 to 4 minutes.
Place a filled kachori with the seam side up, onto a clean surface. Using a rolling pin roll into a circle, approximately 3 inches in diameter.
Heat approx. 1 ½ inches of oil in a frying pan over medium heat. To check if oil is ready, put a little piece of dough into the oil and it should immediately rise to the surface without having changed its color.
Slowly drop kachories into the frying pan making sure they don’t overlap one another. As kachories puff up, slowly turn them over and fry on all sides. Turn kachories 3-4 times until they are golden brown in color, which will take about 7 minutes. Kachories should be crisp. If the kachories are fried over high heat they will be too soft.
Add ¼ teaspoon of salt and 2-3 tablespoons of water to the moong sprouts. Cover and cook over medium heat for 3-4 minutes till sprouts are tender. Set aside.
Gently make an inch sized hole in the center of the kachori.
Fill with 1 tablespoon of sprouts, 1 tablespoon of potatoes, 2 tablespoons of yogurt and a drizzle with both of the 2 chutneys.
As an option, add a little cilantro, green chili and 1 tablespoon of fine Sev. These add a little more texture and flavor to the Kachori.
