This recipe is best using the ripest tomatoes you can find. Place all of the ingredients in a large saucepan over high heat, stir without boiling until sugar has dissolved. Bring to the boil and then reduce heat, simmer, uncovered, stirring occasionally for about 90 minutes or until jam is thick.

Cool for 15 minutes. You can blend this jam for a smooth consistency, but I left it as is with a great relish texture.

To sterilise the jars, wash the jars and lids with hot soapy water, rinsing thoroughly. Place into a 120°C (250°F) oven for 30 minutes or until they are hot and dry. Remove from the oven carefully and pour the hot jam into the jars and seal immediately.

If you make jam regularly, it's always a good idea to label and date your jars so you can keep track of when to use them. Store in a cool, dark place and refrigerate when opened. Jam will keep for about 3 months.
