Quick Answer
Smoke lamb with ironbark wood at 120-135°C (250-275°F) for 5-8 hours (leg or shoulder). Internal temp: 93°C (200°F) for pull-apart, 63°C (145°F) for slicing. Ironbark adds a bold, earthy, distinctly australian flavour.
Why Ironbark Wood for Lamb?
Ironbark is a strong-intensity smoking wood with a bold, earthy, distinctly australian flavour profile. Native Australian hardwood — dense and long-burning.
Ironbark is an excellent match for lamb. Burns extremely hot and long. Use less than you think — ironbark is dense and produces intense smoke. A little goes a long way. Sourced from Australian eucalyptus forests.

How to Smoke Lamb with Ironbark
- Prep the lamb: Score the fat cap. Season with salt, pepper, rosemary, and garlic.
- Set up your smoker: Preheat to 120-135°C (250-275°F). Add ironbark wood chunks (not chips — chunks burn slower and produce cleaner smoke). Use less than you think — ironbark is intense.
- Smoke: Place the lamb on the grate, fat side up. Maintain a steady temperature throughout the cook.
- Monitor: Use a leave-in probe thermometer. Check the temperature regularly.
- Target temp: Cook until the internal temperature reaches 93°C (200°F) for pull-apart, 63°C (145°F) for slicing.
- Rest: Rest for 20-30 minutes before slicing or serving.
Lamb's rich flavour pairs well with mild to medium woods. Go easy on heavy smoke — you want to complement the lamb, not mask it. A butterflied leg cooks faster and more evenly than bone-in.

Wood Pairing Tips
Ironbark is a bold wood. For lamb, consider blending with a milder wood like apple or cherry to soften the intensity. Start with a 50/50 mix and adjust to taste.
Pro tip: Always use seasoned (dried) wood, never green. Green wood produces bitter, acrid smoke. Chunks over chips for a cleaner, longer burn. And remember — thin, blue smoke is the goal. Thick white smoke means your fire needs more oxygen.
