- First peel a small onion and cut it in half. Place a heaping tablespoon of brown sugar in a cup, fill it about halfway up with hot water, then stir to dissolve the brown sugar.
- Once the water has cooled place a half of the cut onion into the cup and blend it until smooth with a hand blender.
- In small bowl combine a 200 gram jar of tomato paste with ½ teaspoon of mustard, ¼ teaspoon of ground cloves, ¼ teaspoon of ground cinnamon, ¼ teaspoon of salt, and 3 tablespoons of white vinegar.
- Then add in the sugar and onion mixture you prepared earlier and whisk it all together.
The simple recipe is very quick and easy to make and you can customize it in a number of ways. If you prefer thicker ketchup don’t add as much of the brown sugar and onion water, and for a more thin, runny ketchup, just add more of it. You can also substitute vinegars, a lot of people like malt vinegar in it, or add in hot sauce for a spicy kick. Experiment with whatever flavors you like! When you’re done just pour the homemade ketchup into an old bottle, or sealed container, and store it in the refrigerator to enjoy later.
