The tomato sauce mixture is on the right. The large pot is for the pasta sauce. With this we have no exact recipe. Some oil, onion and garlic is sautéed first, then zucchinis or other excess vegetables are roughly chopped and added before the tomatoes are added. This is boiled up until mostly liquid, pureed with the stick and then bottled in jars. This large saucepanful filled 18 375g jars which is nearly 7 litres of sauce. Last year we made about 90 jars and ran out a week before the first jar of this season was made.
We use it on pasta, in meatballs, on pizzas and it provides a rich and tasty sauce all year.
