Mix paprika, salt, 1 tablespoon of sugar, chili flakes, garlic, chili powder and cumin. Wash, quarter, core and dice the pears. Peel and finely dice shallots.
Wash the ribs and pat dry. Put shallots and pears cubes, 200 ml wine and 2 tablespoons of spice mixture into a freezer bag. Place the ribs in the bag and close it tightly. Place in the refrigerator overnight.
The next day take ribs out of the bag. Pour the stock, pear juice and 250 ml wine into a pot and let it boil down a little. Put half of the stock in a bowl. Add lemon juice, 2 tablespoons of spice mixture, chilli sauce and 1 tablespoon of brown sugar to the remaining stock, bring to the boil and cook until the mixture is viscous.
Spread the grill briquettes in the grill and preheat well. Grill the ribs on the hot grill for 5-10 minutes on both sides. Take them off the grill and wrap them with the stock from the bowl in aluminium foil to form a firm pack so that no liquid escapes.
Slide the barbecue briquettes onto one side of the barbecue. Place the packs on the other side of the grill and grill indirectly for approx. 1 1/2 hours. If the grill has a lid, close it. Remove the ribs from the packet, brush them with the boiled stock and place them on a grill tray.
Grill indirectly for another 45 minutes. Spread again after approx. 30 minutes.
