Prep ham: Remove ham from packaging, pat dry, and score surface in a shallow diamond pattern (or set spiral-cut slices slightly apart).
Make glaze: In a small saucepan, combine brown sugar, Dijon mustard, maple syrup, apple cider vinegar, olive oil, cinnamon, cloves, and orange zest. Warm over low heat, whisking until glossy (2–3 minutes). Reserve 1 tbsp glaze for finishing.
Preheat air fryer: Preheat to 160°C / 320°F for 5 minutes.
First-stage cook: Place ham in air fryer, scored side up. Brush a thin layer of glaze. Cook at 160°C / 320°F for 25 minutes for ~1.0 kg ham (increase to 30–35 minutes for 1.2–1.5 kg). Brush glaze again halfway through.
Finish & caramelize: Brush a generous layer of glaze. Increase air fryer to 200°C / 400°F and cook 3–5 minutes to caramelize the glaze — watch to avoid burning.
Check temperature: Insert instant-read thermometer into the thickest part. Target internal temp: 74°C / 165°F (for turkey). If not reached, return to 160°C / 320°F in 5-minute increments until it is.
Rest: Tent with foil and rest 10 minutes.
Slice & serve: Slice, garnish with citrus slices and herbs, and drizzle reserved glaze if desired.
