How to Make Bush Spice Lamb Marinade
- Combine: Mix all marinade ingredients in a bowl or ziplock bag until well combined.
- Prep the lamb: Pat the lamb dry with paper towel. Trim any excess fat if needed.
- Marinate: Add the lamb to the marinade, making sure every piece is well coated. Refrigerate for 4 hours minimum, up to 24 hours for deeper flavour.
- Bring to temp: Remove from the fridge 20-30 minutes before cooking to take the chill off. This helps it cook more evenly.
- BBQ: Shake off excess marinade and grill over high heat (220-260°C / 425-500°F) until the internal temperature reaches 54-63°C (130-145°F) depending on preference.
- Rest: Let the lamb rest for 5-10 minutes before serving.
Tips for the Best Bush Spice Lamb
- Don't skip the rest — resting allows the juices to redistribute for a juicier result.
- Use a meat thermometer — the only reliable way to know your lamb is done is by checking the internal temperature.
- Reserve some marinade — set aside a portion before adding raw meat to use as a finishing sauce or baste.
- Oil the grates — clean, oiled grates prevent sticking and give you better grill marks.
Common Mistakes to Avoid
- Marinating too long in acid — especially with citrus or vinegar-based marinades, over-marinating can break down the surface and make it mushy.
- Grilling straight from the fridge — cold meat doesn't cook evenly. Let it come to room temperature first.
- Using the same marinade as a sauce — never reuse marinade that has touched raw meat. Always reserve a clean portion first.
- Overcrowding the BBQ — give each piece space so it sears rather than steams.
