To achieve maximum success in preparing the rustic tart with caramelized onions and gorgonzolahere are some tips that will guide you through the culinary process. Prepare the dough for the tart calmly, ensuring an even distribution of the ingredients. Let the dough rest in the refrigerator for at least 30 minutes; this step will favor the crumbly consistency and ease of processing. Choose quality onions and slice them evenly. Caramelize them slowly to develop deep, sweet flavors. Add a pinch of salt to intensify the flavors. When you roll out the dough, give it a rustic shape to underline the homemade aspect of the preparation. Arrange the caramelized onions and gorgonzola over the pasta, creating a balanced layer of flavors. During cooking, check the browning of the crust to avoid burning. It will be ready when the pasta has acquired a golden color. Bring the dish to the table on special occasions or elegant dinners, as a tasty appetizer or main course. Its versatility makes it suitable for every season; serve it hot on cold winter evenings or at room temperature during the more temperate months.
