Aloo Samose (Indian-Spiced Potato Pastries)

For the dough: Whisk together flour and salt in a large bowl. Add butter, and using your fingers, rub into flour until pea-size crumbs form; add 6 tbsp. warm water, and mix with your fingers until dough forms. Transfer to a work surface, and knead until dough is smooth and elastic, about 12 minutes. Cover with plastic wrap, and chill for 1 hour or up to 24 hours.

For the filling: Heat oil in a 12" skillet over medium heat. Add onion, and cook until lightly browned, about 8 minutes. Add peas, cilantro, ginger, chile, and 3 tbsp. water; cover, and reduce heat to medium-low. Cook, stirring occasionally, until peas are soft, about 5 minutes. Add juice, amchoor, anardana, coriander, garam masala, cumin, cayenne, potatoes, and salt, and cook, stirring, until potatoes are heated through, about 5 minutes. Remove from heat, and set filling aside to cool completely.

Place dough on a lightly floured work surface, divide into 12 equal balls, and cover with a damp towel to keep from drying out. Using a rolling pin, roll 1 dough ball into a 6" round; cut round in half. Gather straight edges of 1 half-round together, overlapping them by 1⁄4" to form a cone; moisten seam with water and press to seal. Spoon 1 heaping tbsp. filling into cone. Moisten inside of top edge of cone with water, press edges together to close top of cone, and pinch along top 1⁄4" of seam to completely seal filling in dough cone. Pleat length of seam by folding over about 1⁄4" of the dough and pinching it together in about 1⁄2" increments. Repeat process with remaining dough and filling to make 24 pastries total.

Pour oil to a depth of 2" in a 6-qt. Dutch oven, and heat over medium heat until a deep-fry thermometer reads 350°. Working in batches, fry pastries until golden brown all over, about 10 minutes. Using tongs, transfer samosas to paper towels to drain briefly. Transfer to a serving platter, and serve hot or at room temperature with Cilantro-Mint Chutney on the side.
