2 cups flour
1 tsp. active dry yeast
1 1/2 tsp. ground cumin
1 tsp. ground turmeric
1/2 tsp. plus 1 tbsp. kosher salt
1/4 tsp. sugar
3 tbsp. vegetable oil, plus more for frying
1 large yellow onion, halved lengthwise and thinly sliced
2 1/2 tsp. curry powder
2 cloves garlic, smashed
6 sprigs cilantro, roughly chopped
1 15-oz. can chickpeas
3 tbsp. tamarind paste
1 granny smith apple
1. In a large bowl, whisk together flour, yeast, 1/2 tsp. cumin, turmeric, 1/2 tsp. salt, and sugar. Add 3/4 cup 115 water and mix with a wooden spoon until a soft dough forms. Turn out dough onto a floured surface. Knead dough until smooth and elastic, about 5 minutes. Lightly oil dough with 1 tbsp. vegetable oil and transfer to a large bowl; cover with plastic wrap. Transfer bowl to a warm place and let rise until it doubles in size, about 1 1/2 hours.
2. Meanwhile, heat 2 tbsp. oil in a 4-quart saucepan over medium-high heat. Add onions and 2 tsp. curry powder and cook, stirring occasionally, until onions soften, 15 minutes. Add the garlic, cilantro, chickpeas, and 1 1/2 cups water. Bring water to a boil over high heat; reduce heat to medium and cook, partially covered, until chickpeas begin to fall apart, about 1 1/2 hours. Mash half of the chickpeas against the side of the saucepan with a wooden spoon. Cover and set aside.
3. Divide dough into sixteen 1-ounce portions and form loose balls. Place each dough ball between 2 sheets of waxed paper and press the dough with your hands into a 1/8"-thick disk about 6" in diameter.
4. Pour in oil to a depth of 11/2" in a 4-quart saucepan; heat over medium-high heat until the oil registers 325° on a deep-fry thermometer. Fry 1 dough portion at a time, inverting once with tongs, until puffed, about 30 seconds. Transfer to a paper towel–lined plate with tongs. Repeat with remaining dough, covering each portion with a paper towel as you stack the doubles on the plate.
5. In a small bowl, whisk tamarind paste with ½ cup warm water and remaining curry powder and cumin. Grate granny smith apple on a box grater and stir to combine. For each double, spoon on 1 tbsp. of chickpeas, add chutney, and top with another double. Serve hot.
