Passata (tomato purée)
For about 1½ litres of passata
Ingredients:
- 2 kg tomatoes
- a pinch of salt (optional)
Instructions:
- Wash the tomatoes, score them in a cross pattern, and blanch them briefly in boiling water. Then cool them quickly in cold water and peel.
- Remove the stems, chop the tomatoes, and strain to remove the seeds and any remaining skin.
- Cook the resulting purée over a low heat for 20–30 minutes, until thickened slightly. Add salt to taste, if desired.
- Pour the hot passata into clean, warmed bottles. Wipe the rims, seal the bottles, and sterilise them in a water bath at 90°C for about 30 minutes.
- Let the jars cool slowly under a dish towel and store in a dark, cool place. They will keep for at least a year.
Tomato soup
Ingredients:
- ½ onion, finely chopped
- oil for sautéing
- 280 g passata
- 250 ml tomato water
- salt and pepper to taste
- a little sugar to taste (optional)
- 1 tablespoon of cream or a pat of butter (optional, to mellow the flavour)
To serve:
- fresh basil
- cheese to taste (for example parmesan)
Instructions:
- Sauté the onion in a little oil until it softens and develops a sweeter flavour.
- Add the passata and tomato water, stir, and simmer briefly.
- Season with salt, pepper, and, if needed, a pinch of sugar to balance the acidity.
- Blend with an immersion blender until smooth. If you want an extra-smooth consistency, you can strain the soup through a sieve.
- Finally, add cream or butter to enrich the flavour and simmer briefly.
- Serve with fresh basil and cheese.
Tomato water
Ingredients:
- 1½ kg tomatoes

Directions:
- Blend the tomatoes with the salt.
