• 5 tablespoons butter
• 1/2 cup chopped onion
• 4 tablespoons flour
• 4 cups milk
• 1/2 bay leaf
• 1 1/2 teaspoons sugar
• 1 1/2 teaspoons salt
• 1/2 teaspoon baking soda
• 3 cups tomatoes, chopped (fresh or canned)
Melt the butter in a soup pot. Add the onion and cook over medium heat, stirring, until the onion is softened but not browned.
Sprinkle the flour over the butter mixture and continue to stir and cook for 1 to 2 minutes. Slowly add the milk, bay leaf, sugar, and salt and continue to cook and stir until slightly thickened.
Stir the baking soda into the tomatoes. Add the tomatoes to the milk, and bring just to a simmer. Remove from the heat and put through a strainer. Adjust seasonings to taste and serve.
