2 Little Gem lettuces, jalapeño chilli slices and half-fat crème fraîche
Heat the slow cooker if necessary. Put the chipotle paste, red onion, garlic, cloves, lime juice and cider vinegar into the slow cooker and stir until combined. Add the bay leaves and stock and then put the beef on top. Use a pair of tongs to turn the meat over a few times in the sauce.
Put the lid on the slow cooker. Cook on High for 1 hour and then Low for 8 hours or until the meat shreds easily when you pull it apart with 2 forks.
Serve with the lettuce cups and jalapeño chilles and crème fraîche.
