NOTES
1. Tomatoes - When tomatoes are in season in the summer, it is nice to make this soup with fresh tomatoes (2 ½ pounds). Use canned tomatoes out of season.2. Vegetable stock - In this recipe, you can use stock cubes or fresh stock if you ensure that the total amount of liquid is 3 cups.3. Season with salt and pepper - Because broth sometimes does and sometimes does not contain salt, it is important to taste the soup at the end (i.e., after adding the roux) and add extra salt if necessary. Do not do this before because when cooking, liquid can evaporate, and the soup may become too salty.4. Crock-pot - Making this soup on the slow cooker’s high setting will be ready in three hours. Turning the slow cooker on low will take 6 hours before the tomato soup is prepared.5. - Storage
Refrigerator: Let the soup cool quickly and cover. This keeps the soup in the fridge for up to 2 days.
Freezer: Cool the soup quickly and place it in an airtight freezer container. Keep ½ inch of the top free (the soup expands slightly due to the freezing). This way, you can keep the soup in the freezer for up to 2 months. Let thaw in the refrigerator.
Reheating: Heat the soup over low heat, stirring, until it is warm.
