The 'Danger Zone' refers to temperatures below 63°C but above 8°C. In this temperature window, bacteria is the most likely to grow. Therefore, if you leave your leg of lamb to defrost at room temperature you are risking harmful microbes growing. This is also why defrosting lamb in direct sunlight or by a radiator should be avoided.
Yes, it is possible to defrost leg of lamb in the microwave. If your microwave is big enough that is! If you are pressed for time, using a microwave for defrosting is definitely an option. However, we would only use this method as a last resort because the results can be inconsistent and the temperature is harder to control. With larger lamb legs especially, the outsides may begin cooking at a low temperature whilst the inside is still trying to defrost. If you must defrost your leg of lamb in a microwave, it's vital you use defrost mode and follow the manufacturer's instructions closely to avoid exposing the meat to the 'Danger Zone'. If using a microwave, you must cook the lamb leg straight away. Do not then store it in the fridge.
