Common Mistakes to Avoid
- Overcooking the lamb: Cooking the lamb shoulder too long can lead to dry meat. Use a meat thermometer to check for doneness, aiming for about 190°F for tender results.
- Skipping the marination: Not allowing the lamb to marinate can result in less flavor. Ideally, marinate overnight or at least a few hours before cooking.
- Ignoring the resting time: Cutting into the lamb immediately after cooking can cause juices to escape. Let it rest for at least 15-20 minutes before slicing.
- Using low-quality ingredients: Cheap mustard or honey can affect flavor. Opt for high-quality Dijon and honey for a rich glaze.
- Not seasoning properly: Under-seasoning can make the dish bland. Ensure you use enough salt and pepper to enhance the flavors.
