How to Serve Italian Penicillin Soup So It Shines
Serve it hot in shallow bowls so the aroma rises. Add a drizzle of olive oil, or a few grinds of black pepper. A slice of crusty bread or a plain roll works well to soak up the broth. For a heartier meal, add cooked pasta or shredded chicken just before serving.
Best Ways to Keep This Soup Fresh
Cool the soup to room temperature within two hours, then store in airtight containers. Refrigerate for up to 4 days. You can freeze the soup for up to 3 months—leave out the lemon and fresh greens if freezing, then add them when reheating. Reheat gently on the stove until warmed through.
