For best flavor, refrigerate soup overnight before serving.
Purchasing Fresh Tomatoes
Ripe tomatoes should be firm and free of any soft spots, bruises or signs of mold. They should have bright shiny skins, feel heavy for their size and boast a lovely fresh tomato fragrance.
How to Ripen Tomatoes
Most tomatoes require some ripening at home. To do so, place tomatoes in a closed brown paper bag and store at room temperature away from direct sunlight. After tomatoes turn red, remove them from the bag and store at room temperature for up to 3 days.
