Combine all of the slow cooker ingredients listed above, apart from the beef short ribs. Stir well.
In a hot pan with a little oil, brown the beef short ribs for a couple of minutes on each side.
Place the browned beef short ribs in the slow cooker, meaty side down.
Cook on low for 7-8 hours or on high for 4 hours.
Carefully remove the beef short ribs and place into a bowl. Remove the bones and shred the meat with two forks.
Tacos
Remove the bay leaves and the cinnamon stick from the slow cooker. With a hand blender carefully blend the rest of the ingredients in the slow cooker to make your consommé. Set the slow cooker to warm.
Put a little vegetable oil in a pan on a medium heat. Carefully dip tortillas into the consommé and fry for 1 minute on each side.
Place shredded beef and grated cheese on one half of the tortilla, carefully fold and fry for a further 1-2 minutes. Optionally add diced red onion and coriander.
Spoon extra consommé into a bowl for dipping the tacos into and enjoy!
