In a large heavy duty saucepot, brown ground pork over high heat. Drain half of the drippings and add onions, carrots and garlic. Reduce heat and cook vegetables 10 minutes stirring often to prevent sticking. Add herbs and tomato paste and cook five to six minutes (This helps to caramelize the tomato paste resulting in a sweeter tomato sauce). Add remaining tomato products and water. Turn heat to low (very low). Allow sauce to cook 3 1 /2 hours, stirring occasionally to make sure the sauce doesn’t stick. Add vinegar.
Yield: three quarts
Sauce is best after two or three days in the refrigerator. Sauce freezes well.
