Make the marinade: Cut the bell pepper into chunks. Roughly chop the garlic and ginger. Place them in a tall container, add the remaining ingredients except the cornstarch and water, and blend with an immersion blender until smooth.1 large bell pepper + 2 garlic cloves + 1 thumb-sized piece of ginger + zest of 1 small lemon + 2 tablespoons lemon juice + 2 tablespoons brown sugar + 4 tablespoons olive oil + ½ teaspoon pepper flakes + 1 teaspoon sweet paprika + 2 teaspoons fine sea salt + ¼ teaspoon ground black pepper
Prepare the drumsticks: Pat the turkey drumsticks dry with paper towels. Place them in a roasting tin and spoon a few tablespoons of the marinade over each one. Brush the drumsticks all over with the marinade. You will only need about ⅓ of the marinade for this step. Reserve the rest to make the sauce after the drumsticks are cooked.2 turkey drumsticks
Bake the turkey drumsticks: Arrange the drumsticks with the side showing less skin facing up. Add ¼ cup of water to the roasting tin and place it in the preheated oven. Bake for 1 hour.
Turn the drumsticks over and add another ¼ cup of water if necessary. If there is still enough liquid in the pan, skip adding water for now, but check again after about 30 minutes; the bottom of the pan should not be completely dry.
Roast the turkey drumsticks for another hour, brushing them with a little of the reserved marinade every 15–20 minutes. Check after about 30 minutes; if the skin is getting too dark, cover the pan loosely with foil.
Rest the meat: Remove the turkey drumsticks from the pan, cover them very loosely with foil, and let them rest while you make the sauce.
Make the sauce: Pour and scrape the pan juices into a small saucepan and add the reserved bell pepper marinade. Bring to a simmer and cook on low heat, occasionally stirring, for 5-7 minutes, until the blended bell pepper loses its raw taste.
Thicken the sauce - optional: In a small bowl, mix the cornstarch with the cold water. Slowly whisk the slurry into the simmering sauce and let it bubble gently until thickened to your liking; it should be smooth, not gloppy. Taste and adjust with salt and pepper if necessary (it might not be).2 teaspoons cornstarch + about 1 tablespoon cold water
Notes
Hands-on work is minimal: Most of the time is in the oven; prep and brushing take only a few minutes.
Turkey drumsticks: Choose ones around 2.5–2.6 lbs / 1.2 kg each for even cooking.
Bell pepper: Red, yellow, or orange all work; red adds a slightly sweeter flavor.
Cornstarch & water: Thickens the sauce; skip if you prefer a thinner sauce.
