What each ingredient does

Tomatoes
Provide the main body, acidity and flavour of the preserved sauce.
Coarse sea salt
Seasons the tomatoes and adds a little flavour during cooking.

The step that matters

Boil the tomatoes until perfectly soft. Thorough cooking softens the fruit and breaks down its cell walls, so the strained tomatoes have a smooth texture. Hot filling into clean, hot containers helps keep the contents safe for storage.
