Tartlets are a very popular sweet preparation in numerous countries, with a history that dates back to classic European pastry. Originally, these small individual pies were born as a way to present delicate and elaborate desserts with various fillings, which could be enjoyed in individual portions. In several Latin American countries, tartlets are known by different names, such as "pastelitos" in Puerto Rico, "tartaletas" in Mexico and Chile, or "piononos" in some regions. Due to European influence, especially French, these preparations usually have shortcrust or butter pastry bases and are often filled with fresh fruit, cream, or dulce de leche, thus showing a cultural fusion in regional gastronomy.
The combination of butter and blueberries is a favorite in modern pastry for their sweet and slightly acidic flavor offered by the berries, balanced with the soft and golden texture of the butter pastry. This specific recipe also includes ingredients like corn syrup and lemon juice that enhance the freshness and natural flavor of the blueberries, making these tartlets an ideal dessert to share on any occasion.
