a confection prepared by beating sugar and egg white into fruit puree (whipped pastille). The porous, foamy mass is usually thickened by blending it with a hot, sticky, gelatigenous syrup made from sugar, starch syrup, and agar (gum pastille) or with a fruit-jelly paste (boiled pastille). Individual pastilles are then formed from the resulting gelled, foamy mass. Depending on the type of pastilles being made, the finished products are left to stand or to dry at high temperatures, either before or after forming. Pastilles must be stored at a relative humidity of 75–80 percent and at a temperature no higher than 20°C.
