For the tomato foam soup, finely puree tomatoes, olive oil, garlic and basil in a blender. Place a kitchen towel on a colander or, even better, hang it over a strainer.
Pour in the puree, tie the cloth and let it drain slowly for at least 3 hours, collecting the juice.
Bring the resulting clear tomato stock to the boil with whipping cream and whip again with a blender.
Preparation Tip:
This tomato soup is lower in calories but no less convincing in taste if you simply omit the cream and serve the clear tomato stock as a cold soup. By the way, the drained juice also forms the basis for fine tomato jelly. Mix 8 sheets of dissolved gelatine with 1 liter of clear tomato juice and finely diced tomato pieces and let everything set.
