Common Mistakes to Avoid
Making Garlic Parmesan Duchess Potatoes can be simple, but a few common mistakes can affect the outcome. Here are some pitfalls to steer clear of:
- Not seasoning properly: If you skip seasoning the potatoes during mashing, they may taste bland. Always add salt and pepper to enhance flavor.
- Using cold ingredients: Cold butter or cream can make the mixture lumpy. Ensure your butter and cream are at room temperature for a smooth texture.
- Overcooking the potatoes: Overcooked potatoes can become watery and mushy. Boil them until fork-tender but not falling apart.
- Not piping correctly: If the mash is too warm when piping, it won’t hold its shape. Allow it to cool slightly before using a piping bag.
- Skipping the garlic roasting step: Roasting garlic adds depth of flavor. Don’t skip this step; it transforms the dish into something special.
