Set your BBQ up to smoke (130c) the lamb using an offset BBQ or snake method if using a kettle BBQ. I used cherrywood as my wood but you can use any type you prefer.
Mix all spices, oil & lemon juice together
Make a few wholes in the lamb by stabbing it with a sharp knife and rub the lamb in the spice rub
Place the lamb in the BBQ ready to smoke and cook it for 6-8 hours until internal temp is 93c (see tips)
Once the lamb hits about 80c wrap it in foil until the desired temperature
Once cooked remove from the heat, wrap in a towel and place in a cooler bag to rest for 30 minutes
The lamb will be soft and should pull away from the bone with ease
Yoghurt Sauce
Finely chop the mint and mix all ingredients together
Salsa
Dice the tomato, cucumber & onion to (similar) bite sized pieces, mix together and set aside
Fries
Cook according to the packet whilst the lamb is resting
Assembly
Warm your yiros either in the oven or on a grill pan
Place the lettuce on the base followed by lamb & fries, top with salsa & yoghurt
Roll up and demolish!
Notes
Tips/Tricks
it’s important to cook the lamb at 120-140c so that it cooks low n slow – this gives a chance for all the fat to melt and the meat to soften
during the cooking process you should spritz/spray the lamb after 2 hours and then every hour of the cook. This helps to keep it moist and for the exterior to soak up the smoke from the wood
resting the meat is INCREDIBLY important – this allows all the juices to redistribute keeping the meat juicy and moist
93c is the internal temperature you are looking for but it’s about touch/feel. Your probe should be able to go through the lamb-like butter – use the temperature as a guideline and your probe as gospel!
on average a lamb shoulder will take 6-8 hours to cook but sometimes it can be quicker or slower. When cooking low n slow timing is never exact.
if your cook finishes quicker than expected then wrap it tightly in a few layers of foil, wrap in a towel and leave it in a cooler or cool bag. It will keep for 1- 2 hours at the desired temperature
