Homemade Ketchup

• 1 large onion, peeled and chopped
• 1 stalk celery, roughly chopped
• 1 2-inch piece fresh ginger, peeled and chopped
• 3 cloves garlic
• 1 chili pepper, deseeded and finely chopped
• 1 roasted red pepper
• olive oil
• 2 pounds fresh tomatoes, chopped
• 3/4 cup red wine vinegar
• Fine sea salt and freshly ground black pepper
• 1/3 cup brown sugar, more or less to taste

1. Place all of the vegetables but not the tomatoes and the ginger, garlic, and chili in a saucepan with a good pour of olive oil, and cook over low heat for 15 minutes.
2. Season with salt and pepper.
3. Add all of the tomatoes and a cup of water.
4. Bring to a boil and simmer until the sauce is reduced by about half.
5. Remove from heat and puree the sauce in a blender or food processor.
6. Or keep in the pot and use an immersion blender.
7. You haven't gone through the annoying bits of peeling and seeding the tomatoes, so now you'll have to double-strain the sauce through a sieve to get out any seeds and skins.
8. Place the strained sauce into a pan and add the sugar and vinegar.
9. Stir well and then simmer until the the sauce takes on the thickness of ketchup.
10. What you have now is ketchup.
