What we love about this recipe is how easy it is to prepare whether you’re a first-time cook or a seasoned BBQ master your whole family will love this!

Let’s get started. In today’s cook, we are using a boneless leg of lamb which was bought from Costco, however, talk to your local butcher and select the best piece of meat you can afford! Remember to buy local or bye-bye local! 

Preparing your meat 

1. Remove the lamb from the fridge 1 hour before you want to cook it, to let it come up to room temperature.

2. Remove all of the excess fat from the lamb

7. Add a small amount of Flaming Coals lump charcoal to one side of the Deluxe SnS Charcoal basket and light using the Flaming Coals Charcoal starter wand.

8. Now fill the rest of the basket with more charcoal, this will catch as the fire spreads across the basket. This method will help maintain temperature throughout the cooking process. 

9. Place your desired flavour of smoking wood in the charcoal basket before placing the lamb leg on the grill.

10. With the help of your EZ Temp dual probe thermometer monitor the ambient temperature of the kettle. The desired cooking temperature is 225-250f.

11. Insert the EZ Temp probe into the leg of the lamb to monitor the internal temperature. We are looking for an internal temperature of 140f or 60c. This is a perfect medium-rare. Remember, you really don’t want to overcook your lamb.
