This simple yet robust tomato soup combines sautéed onions with diced tomatoes and tomato juice, expertly balanced with sugar and chicken base. Finished with a touch of cream, sherry, and fresh herbs, it yields a comforting and flavorful dish that's perfect as a main course or side.
Balancing the acidity of tomatoes is paramount; always start with the lower end of sugar and taste, adjusting incrementally until the desired balance is achieved. The type and ripeness of tomatoes can significantly affect this. For the chicken base, err on the side of caution and add less initially, as it can be quite potent – you can always add more but can't remove it. To enhance richness, consider deglazing the pot with a splash of white wine after sautéing onions, before adding tomatoes. For a silkier texture, you can briefly blend a portion or all of the soup with an immersion blender before adding cream and herbs. Fresh basil and parsley are non-negotiable for the bright, aromatic finish.
