Common Mistakes to Avoid
When making Sweet Potato Kale Gratin, it’s easy to overlook some important steps. Here are common mistakes and how to avoid them.
- Bold phrase: Not slicing sweet potatoes evenly. Ensure that the sweet potatoes are sliced uniformly for even cooking. Use a mandoline if available.
- Bold phrase: Skipping the seasoning. Don’t forget to season your layers with salt and pepper. This enhances flavor throughout the dish.
- Bold phrase: Overcooking or undercooking kale. Sauté the kale just until wilted; overcooked kale can become mushy and lose its vibrant color.
- Bold phrase: Forgetting to let it cool before serving. Allow the gratin to cool for about 10 minutes before slicing. This helps it set for better presentation.
- Bold phrase: Not using enough cream. The cream is essential for a creamy texture. Adjust the amount if your sweet potatoes absorb too much moisture.
