Step by step recipe:

1. 5 min.

   Prepare the flavouring ingredients

   Prepare 1 carrot.
   
   Prepare 3 shallots.
   
   Rinse and dry 1 bayleaf and 1 sprig thyme.
2. 5 min.

   Prepare the meat

   
   
   Trim a 1 kg beef joint.
   
   Pepper and salt all over.
3. 6 min.
   Pour 2 tablespoons oil into a large frying pan on high heat.
   
   When really hot (lightly smoking), add the beef and fry for about 1 minute on each side until browned all over.
   
   Take off the heat.
4. 15 min.
   Grill (broil), rather than fry, 200 g belly (streaky) bacon in thin slices.
5. 5 min.
   Wrap the bacon around the joint and tie in place with food-grade string.
6. 3 min.
   Put the meat into a roasting bag with the flavouring ingredients (carrot, shallots, thyme and bayleaf) and 30 g chilli powder.
   
   You can aslao add 2 tablespoons Clarified butter if you are worried that the meat will be too dry, but this is not essential.
   
   Seal the bag and sit it in an oven-proof dish. Cook for 5 hours at 300°F (150°C).
7. 5 hours
   After this long cooking, you will see that the meat has given off wonderful juices, full of flavour and with very little fat - a feature of slow cooking.
   
   Tip out the contents of the bag into the serving dish and discard the flavouring ingredients. Serve without delay with the your choice of side dishes.
   
   If you will not be serving the roast right away, put it back in the oven to keep hot.
