Add yogurt or cream to your tomato soup for thicker consistency 3. Balance of flavours:
The key to a perfect tomato soup is a balance of flavours. While you get the tanginess from the tomatoes, you also need the creaminess and the characteristic sweetness. Make sure that no two tastes overpower each other. Also, do not add more than two teaspoons of flour or cornstarch, if you are making the soup for two.
