First, on medium heat, melt butter and olive oil in a kadai and saute onion, garlic, and bay leaf.
Add ripe tomatoes and a diced carrot.
Until the color of the tomatoes changes, saute for one minute.
Add water, cover it, and boil it for 10 minutes.
Boil the tomatoes until they are mushy and tender.
Afterward, chill the mixture and remove the bay leaf.
Using no water, mix until a smooth consistency is obtained.
Now strain the tomato paste and throw away the leftovers.
To adjust consistency, add more water.
Bring the soup to a boil before adding sugar, pepper, and salt.
Make sure to thoroughly combine all the spices.
After reducing the flame, stir in cream and all-purpose flour.
Lastly, serve cream-based tomato soup with mint leaf garnish.
