HELP!!! I'm following the recipe someome kindly gave me on a thread of mine, but I'm really confused about when to remove the fat from the mince. Do I have to leave the mince to cool & fat to set before I can move into the next step? I'm literally making it right now and haven't got a clue what I'm doing! Please help  here's the recipe I'm following:
Simply fry off the veg, fry off the mince ( don’t drain the mince. Remove the fat when it is cold and has set. If you drain it you loose all of the beef flavour that has come out too). Mix together in a big pan, add the optional ingredients ( if using) , stir in the Tom purée and add enough water to cover mince mixture. Add stock cubes and bring to boil. Stir and leave to gently bubble for an hour. Taste, add more stock cubes if needed. Add cornflour/gravy granules and freeze in portion sizes.
Sorry, I'm a hopeless cook but trying to learn so I can feed my family a more healthy diet. Really grateful for any help.
