Detailed Instructions with Photos
STEP 1: Wash the tomatoes and cut them into larger pieces. Peel and core the apples and cut them into cubes. Peel and coarsely chop the onions.
STEP 2: Prepare a large pot with a lid. Put the chopped ingredients in it, add salt, sugar, vinegar, and other spices (bay leaves, allspice, pepper, sweet paprika).
STEP 3: Cover the pot with a lid and bring the mixture to a boil. Reduce the heat and simmer at a low temperature for 30 minutes under the lid. Then remove the cover and simmer on low heat for another 3 hours without stirring.
STEP 4: Strain the cooked mixture through a sieve; about two ladles at a time. The strainer will retain the skins and seeds of the tomatoes and the remaining spices.
Always dispose of the leftovers in the waste bucket before pouring the new mixture from the pot into the strainer.
STEP 5: Return strained ketchup to the pot and cook over medium heat until thickened. The cooking time depends on the liquid content of the tomatoes. This takes anywhere from a half-hour to two hours. I cooked my tomato mixture for another 1.5 hours.
STEP 6: In the meantime, clean the jars with screw top lids. I washed them in a dishwasher; they were still hot when I used them.
STEP 7: Carefully pour the thickened ketchup into the prepared jars and seal them with a screw lid tightly. Turn the jars upside down and let them cool completely.
Storage
Store cooled bottles with tomato ketchup in the refrigerator. Ketchup made in this way lasts in the fridge for up to 6 months.
Useful Tips
- How long the ketchup takes to cook depends on the amount of water in the tomatoes. Watery tomatoes take much longer for the ketchup to thicken - maybe an hour or two more. Plan your time carefully and start making your homemade ketchup in the morning!
- Do you like spicy ketchup? Add chili, curry paste, or a teaspoon of hot paprika powder.
- Other appropriate spices for ketchup include ground cinnamon, thyme, and garlic. Experiment and find out which combination of spices you like best.
FAQs
The only correct way to thicken ketchup is to reduce the amount of liquid when cooking. Simmer the ketchup in the pot without a lid until it thickens. Depending on the amount of liquid in the tomatoes, it may take one to two hours for the ketchup to reduce.
I used about 4 ½ lbs of tomatoes, three apples, and four smaller onions in this recipe and got about 4 ½ cups of homemade ketchup.
The shelf life of homemade ketchup depends on how you treat it after cooking. Canned ketchup lasts the longest. However, the method described in this recipe will guarantee that ketchup will last up to 6 months in the fridge.
