Santa Teresa's quince paste cookies are a crunchy delight that combines a quince heart with a soft cookie, creating a perfect balance in every bite. With their careful presentation in a 600 g tin, these cookies are ideal for enjoying at gatherings or as a gift. Their crunchy exterior and tender interior, along with the fruity flavor of quince, make them a perfect companion for coffee or tea. These treats are not only practical but also versatile for presenting variety on the table. Keep the cookies in a cool, dry place and consume them within 15 days after opening to savor their freshness. To enhance their flavor, you can warm them slightly in the oven before serving and add a touch of icing sugar if desired.
