What is the effect of using cornstarch on pastillage during the drying process?

Using cornstarch in pastillage plays a crucial role in maintaining its shape and texture during the drying process. Cornstarch acts as a stabilizing agent, aiding in the formation of a firm structure that helps pastillage pieces hold their intended shapes, such as decorative figures or intricate designs, without warping or collapsing. This stability is essential as pastillage is primarily used for creating detailed decorations, and ensuring that these decorations maintain their integrity is vital for both aesthetics and function.

While cornstarch does contribute to the texture, it's important to note that it doesn’t inherently speed up the drying process, make the pastillage stickier, or reduce moisture retention directly. Instead, its primary function revolves around enhancing the structural qualities, making it easier to work with and ensuring that the finished product is visually appealing and structurally sound.
