SAEDNEWS: Essential Tips and Tricks for Making Long-Lasting Restaurant-Style Tomato Sauce
According to Saednews, Homemade Tomato Ketchup
Ingredients
1 kg ripe tomatoes
2 tablespoons brown or white sugar
2 tablespoons white vinegar
½ cup water
1 tablespoon cornstarch
1 teaspoon each of liquid glucose, onion powder, garlic powder, and red pepper
1 tablespoon salt
Start by removing the skins from the tomatoes. You can peel them carefully with a sharp knife, or make a small X on the bottom of each tomato. Place the tomatoes in boiling water for about 5 minutes, then transfer them to a bowl of cold water. This shock makes the skins much easier to remove.
Once peeled, cut the tomatoes into quarters. Remove the green stem portions and seeds completely.
Place the peeled and seeded tomatoes in a food processor or blend them thoroughly with an immersion blender until smooth. Transfer the tomato purée to a saucepan and cook over low heat. Stir every few minutes to prevent it from sticking to the bottom. After about 10 minutes, add the salt.
Dissolve the cornstarch in the water. Once most of the liquid from the tomatoes has evaporated, add the cornstarch mixture along with the spices and vinegar. Stir thoroughly until everything is well combined.
Continue stirring until the sauce reaches the consistency of commercial ketchup. Once it reaches your desired thickness, remove it from the heat, add the liquid glucose, and mix well.
Allow the ketchup to cool completely. Transfer it to clean, completely dry, airtight containers and refrigerate.

You can use apple cider vinegar if available. It is preferable, but grape vinegar can also be used.
If your tomato purée is very thick, add about ½ cup of boiling water. If it is already thin, there is no need to add water.
The main ingredients in ketchup are tomatoes, vinegar, salt, and sugar. The remaining ingredients and spices can be adjusted according to your taste or omitted entirely. You can also experiment with spices such as thyme, nutmeg, or cloves.
When stored in a sealed container in the refrigerator, this sauce can last approximately 3–4 months.
Avoid using lemon juice when making tomato ketchup.
1 kg tomatoes
1 medium onion
2 large garlic cloves
½ cup apple cider vinegar or grape vinegar
1 tablespoon sugar
½ tablespoon salt
½ tablespoon red pepper

Wash the tomatoes and cut them into quarters. Set them aside.
Coarsely chop the onion and place it in a suitable saucepan with 2–3 tablespoons of vegetable oil. Cook over low heat for a few minutes until the onion becomes soft and translucent. There is no need to brown it.
Cut the garlic cloves in half and sauté them with the onion for about 2 minutes.
Add the tomatoes to the same saucepan and cover with a lid.
After about 20 minutes, the tomatoes should have released their juices and become soft. Transfer the tomato and onion mixture to a blender or food processor, or blend it thoroughly with an immersion blender.
Pass the purée through a fine strainer to remove the tomato skins and seeds.
Return the strained purée to the saucepan. Add the sugar, vinegar, salt, and red pepper. Cook over low heat, stirring occasionally, until the sauce reaches your preferred consistency.
Remove from the heat and transfer the ketchup to clean, dry containers. Seal tightly and store in the refrigerator.

2 tablespoons vegetable oil
5 tablespoons tomato paste
3 tablespoons white or red vinegar
2 tablespoons brown or white sugar
¼ to ½ tablespoon red pepper, according to taste
⅓ tablespoon salt
2 tablespoons lemon juice
½ cup boiling water
Pour the oil into a small saucepan. Add all the ingredients except the water and lemon juice and mix with a spoon.
Place the saucepan over low heat and sauté the mixture well.
Once the tomato paste releases its color into the oil and has been properly cooked, add the lemon juice. Continue cooking the tomato paste over low heat for another 2 minutes.
Add the water and stir continuously until the mixture comes to a gentle boil.
If the ketchup has reached your preferred consistency, remove it from the heat. If it is too thick, add a little more water. If it is too thin, continue cooking over low heat for a few minutes until some of the excess liquid evaporates and the sauce thickens.
Allow the ketchup to cool, then transfer it to a clean container and refrigerate.
The preparation is similar to the tomato-paste ketchup recipe above, with a few changes.
Omit the lemon juice. Instead of boiling water, use cold water and mix 1 tablespoon of cornstarch into it before adding the mixture to the tomato paste.
You can also add spices such as onion powder and garlic powder for extra flavor.
½ small glass of date vinegar
1 teaspoon sugar
1 teaspoon salt
1 teaspoon red pepper
1 teaspoon turmeric
4 tablespoons strained fresh tomato juice
To prepare the tomato juice, grate fresh tomatoes and pass them through a strainer to remove the seeds.
Place all the ingredients in a small saucepan and cook over medium-low heat.
Allow the excess liquid to evaporate until the mixture becomes a relatively thick dipping sauce.
