Put garlic, salt, pepper, paprika, chicken stock powder, worcestershire sauce and olive oil in a bowl and combine to make a paste
Add lamb shoulder to bowl and coat with paste mix, then place into slow cooker bowl (i used a 3.5L for this one)
Pour vege stock and water mix into bottom of slow cooker
Cook on low for 6 hours.
After 6 hours, mix together pepper and roast meat gravy powders with cornflour and aprox 1 cup of boiling water. Once combined pour into slow cooker and stir into the water mix. Cook for further 30mins-1hour until thick and rich. If too thick add a little more water to grt desired gravy consistency.
To serve, slice meat and then pour gravy over the top.
I served with steamed broccoli and sweet potato bake
Can use a larger piece of shoulder as the paste mix is quite generous. Cooking time may vary for larger pieces (up to 8 hours on low).
