Cut the tomatoes into large wedges.
Chop the onion into strips - first, divide the onion into 2 halves, then cut lengthwise.
Chop the garlic and basil.
Place the tomato slices in a saucepan, pour in 1-1.5 cups of water. Wait until the water boils, then simmer under a lid on low heat for 15 minutes.
While the tomatoes are stewing, fry the onion in olive oil until golden brown. Remember to stir it so that the onion does not burn.
Add freshly fried onions, chopped garlic and basil to the tomatoes.
Add salt and pepper to taste, cream and heat. Remove the soup from the heat, let it cool slightly and blend until pureed. Done!
