Description

Homemade green tomato jam is a rare treat you’ll never find on supermarket shelves. With its tangy-sweet balance, warming spices, and old-fashioned charm, it’s perfect for breakfast toast, pairing with cheese, or gifting to loved ones.


Ingredients

Scale
  • 880 g green tomatoes (diced, about 8 cups of 250 ml each)
    320 g granulated sugar (about 5 cups)
    1 cinnamon stick
    3 cloves
    2 to 3 star anise
    ½ lemon (sliced into rounds)


Instructions

  1. Deseed and dice the tomatoes: With a sharp knife, remove the seeds and cut the tomatoes into even cubes. You should have about 5 cups in total.
  2. Transfer to a pot: Place the diced tomatoes directly into a heavy-bottomed saucepan.
  3. Add the other ingredients: Mix in the sugar, cinnamon stick, cloves, and half a lemon sliced into rounds.
  4. Bring to a boil: Stir well, then heat over medium-high until the mixture reaches a rolling boil.
  5. Cook for 20 minutes: Let it boil, stirring more frequently as it thickens to prevent sticking.
  6. Simmer gently: Reduce the heat and continue cooking at a low simmer for another 25 minutes, stirring often.
  7. Check the texture: After about 30 minutes, natural pectin from the tomatoes should begin to thicken the jam. If it’s still runny, cook a few more minutes.
  8. Remove from heat: Take out the cinnamon stick before filling the jars.
  9. Jar the jam: Pour the hot jam into sterilised jars using a ladle and funnel, leaving 5 mm of headspace.
  10. Seal the jars: Wipe the rims clean with a cloth, place the lids on, and screw tightly.
