Grainy royal icing is usually caused by undissolved sugar, often from not sifting powdered sugar, using coarse sugar in meringue powder, or not mixing the meringue powder with water long enough (frothing it). Other culprits can be high humidity, adding too much liquid, or overmixing on a high speed, which incorporates air and creates a crunchy texture.

The key signs are its visual appearance and poor drying performance, contrasting with smooth, dense, and hard-drying icing.
