Common Mistakes to Avoid
Making a delicious Sourdough Pesto Grilled Cheese can be easy, but there are some common mistakes to watch out for.
- Using stale bread: Fresh sourdough is key. Always use bread that is soft and fresh for the best texture.
- Overloading with cheese: While cheese is delicious, too much can make the sandwich soggy. Stick to the recommended amount for a perfect melt.
- Skipping the drying step: Not drying the mozzarella can lead to excess moisture. Make sure to pat down the mozzarella slices before using them.
- Neglecting to butter the bread: Butter creates a crispy crust. Don’t skip this step, as it enhances flavor and texture.
- Cooking on high heat: Cooking too quickly can burn the bread without melting the cheese. Use medium-low heat for even cooking.
