Bring a pot of water to a boil. Have ready a large bowl of iced water. Plunge whole tomatoes in boiling water until skin starts to peel, 1 minute.
Remove with slotted spoon and place in ice bath.
Let rest until cool enough to handle, then remove peel and squeeze out seeds. Chop 8 tomatoes and puree in blender or food processor. Chop remaining two tomatoes and set aside.
In a large pot or Dutch oven over medium heat, cook onion, bell pepper, carrot and garlic in oil and butter until onion starts to soften, 5 minutes.
Pour in pureed tomatoes. Stir in chopped tomato, basil, Italian seasoning and wine.
Place bay leaf and whole celery stalks in pot. Bring to a boil, then reduce heat to low, cover and simmer 2 hours. Stir in tomato paste and simmer an additional 2 hours. Discard bay leaf and celery and serve.
