Cornstarch plays a significant role in modifying the texture and structural integrity of pastillage once it is dry. When cornstarch is incorporated into pastillage, it acts as a binder and contributes to the overall firmness of the material. This strengthening effect comes from cornstarch's ability to absorb moisture and create a denser, more robust network when it sets, which enhances the stability of the pastillage.

Cornstarch also helps prevent the pastillage from becoming overly hard or brittle, ensuring that it maintains a desirable texture that can withstand handling and shaping. Therefore, its inclusion is fundamental to achieving the optimal performance of pastillage in various applications, such as decorative work or structural components in cake design.
