3. Chop it up into blocks about the size of, say, 20 benson & hedges, or maybe matchboxes. Cook it for ages in the 2l of coke. I've tried coke and Pepsi, but always full fat. I haven't tried cherry or vanilla yet. You literally cannot over cook it. You'll know when it's done because two forks will pull it apart like tissue paper. 3h at 180 will probably do it in a le crueset. I just did 5h in a morphy richards slow cooker on medium, and that was awesome.
