I love home-made ketchup, and it’s even more satisfying making it from home-grown tomatoes.
In the past, I’ve made several batches with red tomatoes and a couple of batches with green ones but this is the first batch I’ve made with beautiful orange sungold tomatoes, a variety we’ve been growing for the last few years. Sungold is a cherry tomato variety and naturally super sweet, so a lot of the harvest doesn’t even make it indoors, or last long if it does. But our plants are giving us plenty this year, both those in the greenhouse and the ones outside. I was keen to see if I could preserve the vibrant colour in a ketchup to enjoy once the growing season is over.
I used my maternal grandfather’s Spicy Tomato Ketchup recipe – the same one I’ve used before. I had 940 grams of tomatoes, so I halved the recipe and made some minor adjustments to spices as well.
Spicy Sungold Tomato Ketchup
1 kg ripe sungold tomatoes
Half a small onion, diced
1-2 garlic cloves, peeled and chopped
Whole spices in fabric bag *
2 black cardamoms, cracked open to release flavours
Half teaspoon whole black peppers, cracked open to release flavours
Half teaspoon cumin seeds
1-2 small pieces of cinnamon or cassia bark
Half teaspoon nutmeg, freshly grated if possible
1 teaspoon chilli powder (or to taste)
2 level teaspoons mustard powder
40 grams sugar (with extra available to adjust to taste)
50 ml cider vinegar (with extra available to adjust to taste)
1 teaspoon salt
* Instead of wrapping my whole spices in muslin tied with string, I use fill-your-own teabags for speed. These are easy to fish back out of the pot and throw away once used.
- Sterilise your jars and lids. I boil my lids in a pan on the stove for 20 minutes before laying them out to dry on a clean tea towel. I sterilise my glass jars in the oven, leaving them in until I’m ready to fill them.
- If you like, you can cut the tomatoes in half, or just slash each one, which makes it easier for them to break down more quickly, but as the sungolds are small, I put them in the pan whole and squish occasionally with a wooden spoon as they cooked.
- Place tomatoes, onion, garlic and bag of whole spices into a large pan. Add a couple of tablespoons of water to stop the tomatoes catching at the bottom before they release their own juices.
- Cook until soft.
- Allow to cool a little. Remove spice bag.
- Blend into as smooth a puree as you can.
- Press through a sieve to remove skin and seed residue.
- Place the sieved liquid into a pan with the nutmeg, chilli powder and mustard powder and bring to the boil.
- If your liquid is quite thin, boil longer to thicken. The time this takes can vary wildly. In the past it’s taken half an hour. This time, I found the liquid was reasonably thick after 5 minutes boiling.
- Add the vinegar and sugar and continue to cook until the sauce reaches ketchup consistency.
- Add salt.
- Taste and add additional vinegar or sugar, if needed.
- Remove the sterilised jars from the oven and pour the ketchup into them while both ketchup and bottles are still hot.
- Seal immediately.
- Once cooled, you can label and store in a dark cupboard.
Please note: As this recipe has only a small volume of sugar and vinegar (both of which are preserving agents), you may prefer to store the ketchup in your fridge and use within a few weeks. We have stored it in a dark cupboard, eaten it many, many months after making, and found it fine. However, we are not experts in preserving or food safety, so please do your own research and decide for yourself.

wow, the colour alone is worth making this ketchup for… glorious… fab recipe x
Thank you Dom, I do love Sungold toms!
Think this is one of my fave recipes of yours! The mix of spices with yellow tomatoes sound lickably good. I will be making this one x
Thanks Deena, recipe is courtesy of my grandfather, via my mum!
This looks delightful, both visually and in terms of the spices in the recipe.
Nana would have been so proud of you! We all used to love his ketchups, jams, jellies, chutneys and pickles 🙂
Aaw, it makes me happy to use his and your recipes.
Hi, looks gorgeous, could you tell me how many jars/bottles this recipe makes I can’t see any mention, would like to make sure I sterilise enough, thank you
This one made 3 and a bit bottles, as shown, but the exact amount varies depending on the fruit itself not to mention just how much you decide to reduce it during the thickening stage.
I *think* those bottles are 250 ml each but I’ll need to double check for you.
That said, I usually sterilise a couple of extra bottles each time just in case, since the sterilising process doesn’t do them any harm in any case. I use the oven method for the bottles and boil the lids.
