Details that make a difference

Good to know before you cook

Whole tomatoes with their juice

Use whole peeled tinned San Marzano tomatoes in this version. Oven-roasted Juanita tomatoes belong in the other tomato soup.

Thicker or lighter

For a thicker soup, hold back some stock and adjust after blending. Add more if it becomes too concentrated.
