Homemade Tomato Ketchup Jamie Oliver Recipes

Steps:

• Heat oil in large non-stick skillet. Add onions and salt. Sweat onions for 15 minutes until soft, translucent and sweet.
• Combine fennel seed, coriander seed and cloves in a mortar, spice grinder or flavor shaker. Grind well. Add to onions with ginger, garlic and chile pepper. Add black pepper and salt.
• Quarter tomatoes and add to pan. Tear basil leaves off of stems and reserve. Chop stems coarsely and add to pan. Add tomato puree, vinegar and brown sugar. Bring to a boil, reduce to medium, and simmer 30-40 minutes.
• Roughly chop basil leaves. Turn off heat and add basil; stir well.
• Transfer to blender and puree smooth. Work in batches, filling the blender jar no more than half way. Pour into a fine sieve and push through.
• Sterilize some ketchup bottles and a funnel, either in boiling water, or dry in a roasting pan in a hot oven. Stir ketchup well and transfer to bottles. Fill bottles completely before sealing. Allow to cool completely, then store in a cool dark place for up to 6 months. Refrigerate after opening.

Steps:

• Place all the vegetables in a large heavy-bottomed saucepan with a big splash of olive oil and the ginger, garlic, chili, basil stalks, coriander seeds and cloves. Season with the pepper and a good pinch of salt.
• Cook gently over a low heat for 10 to 15 minutes until softened, stirring every so often. Add all the tomatoes and 1 1/2 cups of cold water. Bring to the boil and simmer gently until the sauce reduces by half.
• Add the basil leaves, then whiz the sauce in a food processor or with a hand blender and push it through a sieve twice, to make it smooth and shiny. Put the sauce into a clean pan and add the vinegar and the sugar. Place the sauce on the heat and simmer until it reduces and thickens to the consistency of tomato ketchup. At this point, correct the seasoning to taste.
• Spoon the ketchup through a sterilized funnel into sterilized bottles, then seal tightly and place in a cool dark place or the refrigerator until needed - it should keep for 6 months.

Steps:

• In a large heavy pot heat the olive oil over moderate heat and cook the onion until golden brown, stirring occasionally, about 8 to 10 minutes. Add the garlic and cook for another minute.
• Add the tomatoes, vinegar, corn syrup, cloves, allspice, mustard seeds, celery seeds, salt and pepper stirring to combine. Bring the mixture to a boil, reduce heat and simmer, stirring occasionally, for 1 hour.
• Pass the mixture through a food mill (or cheesecloth) into a bowl and return to the pot. Bring the mixture back to a simmer and cook until very thick, stirring occasionally, about 45 minutes. Allow the ketchup to cool.
