Note: Given to me by the mother of a guy I dated in college. Kathy was a great cook. 4B's is a popular family diner found in several of Montana's cities. She talked the restaurant into sharing their most popular soup recipe. So excited that she made it for us one day and I was able to get the recipe from her.
32 oz. can of diced tomatoes
9 oz. can chicken broth
1 oz. butter
2 T. sugar
1 T. chopped onion
2 C. (1 pint) cream or half and half
pinch of soda
Simmer one hour except cream. Heat cream in microwave oven and add the hot tomato mixture to the cream. Makes 1/2 gallon.
