Easy Tomato Jam Made with Canned Tomatoes

1. 1

   I used 2 400 g canned of diced tomatoes.

2. 2

   Most tomato cans sold at the supermarket are 400g.

3. 3

   These are all the ingredients you need.

4. 4

   Use a pot that withstands acid, like an enamel pot.

5. 5

   Put in the tomatoes, sugar (80-90% of the amount indicated) and lemon juice in the pot, mix and start cooking over medium heat.

6. 6

   When it comes to a boil, scum will rise to the surface, so scoop off diligently.

7. 7

   When most of the scum is removed, lower the heat a bit and simmer for about 30 minutes while stirring occasionally.

8. 8

   Sterilize storage jars in the meantime.

9. 9

   Put the jars in a large pot of water.

10. 10

    Boil the jars for about 5 minutes.

11. 11

    Take out, drain and leave to dry.

12. 12

    After 30 minutes, it will have reduced quite a bit.

13. 13

    Taste now and adjust the sweetness.

14. 14

    If you think it's not sweet enough, add the rest of the sugar.

15. 15

    Simmer for another 5 minutes and it's done.

16. 16

    Simmer to the level you like.

17. 17

    Pour the jam into the sterilized jars while it's still piping hot.

18. 18

    Fill the jars up to the rim.

19. 19

    The jars and jam are both very hot, so be careful.

20. 20

    As soon as the jars are filled, turn upside down and leave them as is.

21. 21

    The heat of the tomato jam will disinfect the lids.

22. 22

    When the jars have cooled, the lids will have popped inwards.

23. 23

    It looks like this when it's done.
