As promised, here is the recipe. I took this while actually cooking the sauce for tonight's fellowship dinner. Here is what you need:
Ingredients:
Garlic, Onion, Carrot, Celery (chopped finely)
Bacon
Minced Beef (I used 1kg)
Minced Pork (1/4 kg)
Canned tomatoes
Tomato Sauce
Mushrooms
Some herbs
Believe it or not, I did not use add any oil or salt other that what is found in the ingredients above. But well, there are other tricks.
Begin by frying the bacon until the oil comes out. The bacon provides all the salt and oil you will need for the whole sauce.
When there is some oil from the bacon, add the garlic, onion, carrots and celery. Cook until some of the vegetable juices has come out. Add some water to help this along.
When the vegetables are about 75% of their original size add the mushrooms and cook until everything soft. Add some herbs at this stage, oregano, mixed Italian herbs and tarragon was what I added.
Add the meat cook until the meat has browned. Notice that the volume of the ingredients has not changed. Everything should "shrink".
Add the tomatoes and tomato sauce. Instead of canned tomatoes, you can use fresh tomatoes. But you will have to buy the really expensive deep red roma tomatoes, which cost something like a dollar each. And you will have to buy a lot and de-skin it before using, so it's quite a hassle.
No extra salt or oil added. All the salt and oil came mainly from the bacon and the canned tomatoes and tomato sauce. If you choose to use fresh tomatoes, you will definately need to add some salt, and even some sugar get rid of the bitter taste.
Enjoy!
