This fresh tomato bisque is thickened with a roux to make a rich, creamy, velvety soup.
Run the tomatoes through a food mill to remove the seeds and skins, and place in a large pot over medium heat. Stir in the bouillon, sugar, salt, bay leaf, basil and pepper. Bring to a boil, then reduce heat, and simmer 30 minutes. (If you're going to can this mixture, process it now.)
Melt butter in a small saucepan over medium heat. Whisk in flour all at once to form a roux; cook for 1 minute. Whisk in milk, a little at a time, cooking and stirring constantly until thickened. Stir into tomato mixture and heat through.
