When Winter comes, we are suddenly looking for tomato (and other) sauces to make soup out of, add to lentil braises, vegetable stews, gratins, dipping sauces, and other dishes. Luckily I often make several of these each Autumn so that they are frozen, ready for the first Wintery dish that needs them.
Some of these sauces are the sort of sauce that you put on your (vegetarian) bangers and mash or over your BBQ’d veggies and patties. But the other purpose of these sauces is to add flavour to dishes, or form the base for soups, other sauces, and dipping sauces for snacks.
I have about 7 or so different tomato sauce/puree recipes that get repeated. Autumn is ideal to make them - tomatoes are at their best, especially if home grown. You can, of course, bottle /preserve them instead of freezing.
