Making ketchup is pretty simple, and the payoff is huge. This Homemade Ketchup is tasty and doesn’t include the unwanted ingredients that store bought ketchup has. Keep refrigerated in an airtight container for up... to 3 months. If it lasts that long!
Heat olive oil in a skillet over medium-high heat. Add the onions, ginger, garlic and fennel. Cook until the onions and fennel have softened, about 7 minutes.
Add the chopped tomatoes, tomato paste, grape or cherry tomatoes, water, salt, coriander seeds, sweet paprika, and cloves. Cook over medium heat, until the sauce has reduced by about half, about 10-15 minutes.
Pour the tomato mixture into a food processor and blend until smooth. Pass through a fine sieve, and pour back into the skillet. The mixture should now be shiny and very smooth.
Stir in the vinegar and brown sugar and cook over medium heat until it reaches the consistency of ketchup, about 15-20 minutes. Pass through the sieve again if necessary then cool and serve or store refrigerated in an airtight container.
In the summertime when tomatoes are at their peak and abundant, make a batch or two of this for the winter.
