Crush the garlic with the flat side of a knife.
Bring the extra virgin olive oil (and lard, if using) to medium high heat, then add the garlic and chopped parsley.
After a minute, add the ground beef and break up with a wooden spoon. Add some salt, and cook until it begins to dry up, then add the tomato passata/purèe/chopped tomatoes of your choice.
If using Mutti, they tend to be thick, so add about ¾ cup (177 ml) of water or until the bottom line of the jar (shake to rinse) then add to the pot. If you're using another brand, rinse the can/jar with a little less water, unless it's very thick.
Put the burner on high to bring the sauce to a simmer, and add more salt. Don't be afraid to add Kosher/sea salt as I can guarantee you will have much less sodium in this sauce than a jar of store-bought.
Lower the heat so that the sauce simmers gently for about an hour, stirring occassionally (so that the sauce won't stick). Taste for seasoning after about 30 minutes, and add salt if needed.
When the sauce is ready, check once again for seasoning. Add salt and pepper as desired, and a generous amount of fresh basil, torn into pieces.
