Here is a recipe for Tomato Soup. It uses onion and carrots apart from tomatoes.
Tomato, Onion, Carrot, Garlic and Ginger
Chop everything fine
Heat a table spoon of oil
Add Ginger and Garlic, stir for a few seconds and then add the onions. Keep stirring for about 10-15 seconds
Add the tomatoes, stir
Add a tea spoon of salt and keep stirring
Now add sugar. The quantity depends on how sweet you want the soup to be, bit a table spoon or two is fine with so many tomatoes
Once water starts releasing, reduce the heat to minimum. Add 500ml of water.
Cover the pot and simmer for at least half an hour.
After half an hour or so the water ill be reduced. As long as the soup does not burn it is fine as you can always add water later on.
To lend that professional touch use a blender to thoroughly chop and mix the pieces.
This is what remains after sieving the soup. The liquid has a rich creamy texture.
To complete the soup add water, salt and black pepper to your taste. In case it is a bit sour add sugar bit by bit.
Enjoy.
NOTE
like all stock, you can store the soup after sieving it. If so then the less liquid the better. When making soup add water and seasoning to your taste and you have a soup ready in as much time as it takes to heat it.
