1Remove the string (if present) and rinse under a cold tap. Trim all visible fat from the beef joint and put to one side.
2Finely cut the chillis then grind up into a powder and add to everything else in the slow cooker. Roll the meat in the mixture to cover and cook on low for 8 hours. (In the picture around the beef you can see two large carrots I cut in half)
3When cooked, remove the meat and pull it apart with a fork and place into a large bowl. Add some sauce from the slow cooker into the bowl and mix in for added flavour.
4I don't like to waste things so with the fat, I freeze this until I have enough then simmer it down, remove any solids and use it for roasting potatoes.
