FOR THE KOFTE: Process pine nuts, garlic, paprika, salt, cumin, pepper, coriander, cloves, nutmeg, and cinnamon in food processor until coarse paste forms, 30 to 45 seconds. Transfer mixture to large bowl. Add lamb, onion, parsley, mint, and gelatin; knead with your hands until thoroughly combined and mixture feels slightly sticky, about 2 minutes. Divide mixture into 8 equal portions. Shape each portion into 5-inch-long cylinder about 1 inch in diameter. Using 8 (12-inch) metal skewers, thread 1 cylinder onto each skewer, pressing gently to adhere. Transfer skewers to lightly greased baking sheet, cover with plastic wrap, and refrigerate for at least 1 hour or up to 24 hours.
FOR A CHARCOAL GRILL: Using skewer, poke 12 holes in bottom of disposable pan. Open bottom vent completely and place pan in center of grill. Light large chimney starter filled two thirds with charcoal briquettes (4 quarts). When top coals are partially covered with ash, pour into pan. Set cooking grate in place, cover, and open lid vent completely. Heat grill until hot, about 5 minutes.
FOR A GAS GRILL: Turn all burners to high, cover, and heat grill until hot, about 15 minutes. Leave all burners on high.
