• Bold seasoning: Forgetting to taste and adjust seasoning can leave your soup bland. Always season gradually and taste as you go for optimal flavor.
• Bold broth choice: Using low-quality broth can affect the soup’s richness. Opt for homemade or high-quality low-sodium chicken or vegetable broth.
• Bold cream addition: Adding cream too early can curdle it. Stir in the heavy cream at the end when the soup has cooled slightly.
