Caramelized Vidalia Onion Soup
The recipe can be prepared through Step 3 up to 1 day ahead. Refrigerate the soup and store the croutons separately in an airtight container.
Vidalia onions, from outside the town of Vidalia, Georgia, are available in the spring and summer, but you can use any sweet onion, like Mayan sweets, instead. Because sweet onions contain more liquid than regular onions and are more fragile, with thinner skins, they should be stored in the refrigerator in a paper bag rather than in the pantry.
