Famous Tomato Ketchup Recipes

Steps:

• Preheat the broiler. Toss the onion slices with the olive oil and broil them until charred, about 8 minutes on each side.
• Put the onions and all the remaining ingredients in a deep heavy nonreactive pot. Simmer uncovered over low heat for about 3 hours, stirring every 15 minutes to break up the tomatoes and to keep the ketchup from sticking to the bottom of the pot. The mixture will thicken.
• Puree the ketchup in batches in a food processor or blender. If the puree seems too thin, return it to the pot and simmer until it is as thick as you like it. This ketchup keeps well refrigerated for up to 4 weeks.
• Heat a skillet over medium heat until hot. Add the cumin seeds and toss occasionally until lightly toasted, about 1 minute. Transfer to a plate to cool, and repeat with the coriander seeds and then the mustard seeds. Be careful that the spices don't burn. You'll know that they're done when a toasty, nutty aroma rises out of the pan. When the seeds are cool, coarsely grind them together in a spice grinder or in a mortar with pestle.

Steps:

• Heat a medium saucepan over medium-low heat and whisk in the tomato paste, 2 tablespoons each of the cider vinegar and brown sugar and 1/2 cup of the water. Season with the onion, garlic and mustard powders along with the celery salt, cinnamon, allspice, cloves and salt.
• Bring to a simmer then reduce the heat to low and cook for 30 minutes, stirring frequently and adding more sugar or vinegar if desired and more water to reach your desired consistency.
• Season to taste with more salt, if needed, and allow to cool before transferring to a bottle or jar and storing in the fridge for up to 1 month.

Steps:

• In a wide skillet, simmer tomatoes, vinegar, sugar, salt and pepper until a thick jamlike mixture forms and liquid evaporates, 20 to 25 minutes. Purée until smooth. Strain through a fine-mesh sieve. (For a perfectly smooth texture, strain twice.) Stir in Worcestershire. Chill before serving.

Steps:

• Pour ground tomatoes into slow cooker. Swirl 1/4 cup water in each emptied can and pour into slow cooker. Add sugar, vinegar, onion powder, garlic powder, salt, celery salt, mustard powder, black pepper, cayenne pepper, and whole clove; whisk to combine.
• Cook on high, uncovered, until mixture is reduced by half and very thick, 10 to 12 hours. Stir every hour or so.
• Smooth the texture of the ketchup using an immersion blender, about 20 seconds.
• Ladle the ketchup into a fine strainer and press mixture with the back of a ladle to strain out any skins and seeds.
• Transfer the strained ketchup to a bowl. Cool completely before tasting to adjust salt, black pepper, or cayenne pepper.
