Made the tomato soup from a big can of those San Marzano tomatoes. I found a couple of 280z. cans in the bargain basket at Kroger a while back and this last one sat in the cupboard till I had this flash of inspiration.
Mince a carrot and half an onion and sweat them down in butter in a sauce pan. Sprinkle a bit of flour on the veggies and stir for a minute, then add chicken stock and a can of tomatoes. Season with celery salt, a pinch each of nutmeg, ground cloves, and black pepper and bring to a simmer for half an hour or so. Let cool a bit, then puree in a blender or with a stick blender. I like the stick blender because it’s easier to clean up. Add more chicken stock if it looks too thick. Some folks like to add cream right before serving but I never did eat it that way.
