1. To make the matzah balls, puree the onions in a food processor. Transfer to a large bowl, and whisk in the egg, garlic, cardamom, turmeric, oil, 2 teaspoons salt, and several grinds of pepper. Mix in the chickpea flour and chicken to form a thick paste. Cover and store the dough in the refrigerator for at least 4 hours, or up to 24 hours, to firm up.
2. Wet your hands with cold water and break off walnut-size pieces of the dough. Roll them into smooth balls, to make a total of 30 balls.
3. In a large stockpot, bring the 12 cups stock and 2 teaspoons sea salt to a rapid boil.
4. Carefully drop the dumplings into the stock. Turn down the heat to low, cover, and simmer for 50 minutes without opening the pot. When ready, the gondi will be firm in the center. Remove them with a slotted spoon. The cooking stock can be strained and used for the soup broth, or reserved for another use.
5. In a second stockpot, combine the 8 cups stock, carrot, and chickpeas and bring to a boil. Pierce the limes several times with a fork and add them to the stock along with their soaking water. Lower the heat and simmer, covered, for 15 minutes. Add the herbs and season to taste with salt and pepper. Stir in the lemon juice just before serving. Divide the gondi among soup bowls, ladle the broth over the top, and serve.
