Notes
You can use any variety of tomato. Using garden tomatoes or what’s fresh at the market is what makes this such a beautiful recipe. Have yellow tomatoes? Green tomatoes? Use those. Roma tomatoes are a bit meatier and also a good choice.
If needed to thin the soup out, add a bit of water, vegetable broth, or chicken broth.
