>>23774725Incorrect method for cooking minced beef.
You cook the beef in some olive oil and stir it until it's brown and then leave it and wait for the water to evaporate.
Then once the water is gone it will start to fry instead of boil and you'll get some amazing smelling smoke coming off of it, you'll need to keep a good eye on it at this point to avoid burning it. You'll know it's done because parts of it will go brown like the crust on a steak.
Then tip it all out and fry your onion in more oil and then add the beef back when you're ready to add the tinned chopped tomatoes and passata.
