Tomato sauce put away for winter preserves the best flavours of summer: the taste of ripe tomatoes for winter pasta and meat dishes. Old recipes put away one litre from 2 kg of tomatoes; today the onion and lemon juice make it tastier and safer. Sterilising in a water bath protects the sauce from spoiling.
Wash the tomatoes, cut out the stems and cut into quarters. Peel and finely chop the onion.
Cook the tomatoes with the onion in a large saucepan without water over low heat for 20 minutes, until the skins come away and the tomatoes fall apart.
Push the mixture through a sieve or blend smooth with a hand blender and return to the pan. Season with salt and sugar and cook over low heat for 30-40 minutes, stirring occasionally, until thick and reduced by half.
Put a teaspoon of lemon juice in each clean, sterilised jar, then fill with the hot sauce to 1 cm below the rim. Wipe the rims and seal at once.
Place the jars in a large pot, cover with water up to the neck and boil for 20-25 minutes from the boil. Take out, let cool upside down, and store in a cool, dark place. After opening keep in the fridge and use within 5 days.
