Spiced Sweet-and-Sour Ribs

Preheat oven to 300°F with rack positioned 8 inches from heat source. Using a paper towel, pull membrane off back of ribs, and discard. Using a boning knife or paring knife, trim 1/2 inch of meat from the thin ends of the ribs to reveal the bones; scrape the exposed bones clean.

Cook caraway, coriander, fennel, and cumin in a small skillet over medium, stirring and swirling skillet often, until toasted and fragrant, about 2 minutes. Transfer mixture to a spice grinder. Let cool about 5 minutes. Process until ground into a coarse powder, about 30 seconds.

Sprinkle ribs generously with salt and pepper to taste; rub ribs all over with ground spice mixture. Place ribs, meaty side up, on a broiler-safe wire rack set inside a large rimmed baking sheet. Roast in preheated oven until tender but not falling apart, about 2 hours and 15 minutes.

Meanwhile, heat oil in a medium saucepan over medium. Add onion and 1/8 teaspoon salt; cook, stirring occasionally, until softened, about 5 minutes. Add vinegar, balsamic reduction, and maple syrup. Bring to a simmer over medium-high; simmer, stirring occasionally, until thickened and reduced to about 2/3 cup, 5 to 8 minutes. Remove from heat.

Remove from oven; flip ribs, and brush top with some of the glaze. Return to oven; broil until browned on other side, 1 to 2 minutes. Remove from oven; flip ribs, and brush with remaining glaze. Continue broiling until ribs look sticky and shiny, 1 to 2 minutes.

Transfer ribs to a carving board; let rest 5 minutes. Cut ribs between bones to separate, and mound ribs on a serving platter
