Tomato Basil / Coriander Soup

It has been raining heavily here and what better way to enjoy the rains than by having a hot bowl of soup with crusty bread? And this soup is so easy to make!

Tomato - 1 kg, chopped
(If you have the patience blanch and skin and deseed, otherwise just chop fine, like I did!)
Basil / Coriander stalk - 1 handful
Tomato ketchup - 2 tbsp
Onion -1, chopped
Garlic - 4 cloves, chopped
Celery (opt) - 1 stalk
Salt
Pepper
Sugar - 1 tbsp
Cream (opt) - 1 tsp per bowl
Butter / Olive oil / Vegetable oil - 1 tbsp

Heat the oil/butter and saute the onion, garlic and celery on a low flame till translucent.
Now add the tomato, salt, pepper, sugar and tomato ketchup.
Cover and cook for 15 minutes.
Add the chopped basil / coriander stalk and cook covered on low flame for a further 5 minutes.
Now you need to blend this and adjust seasoning.
Then reheat just before serving.
Serve with croutons and swirls of cream.
