Fondant icing sugar syrup, produced by processing fondant with invertase. Fondant fancies are a type of cake typically coated in poured fondant. "Rolled fondant," "fondant icing," or "pettinice," which is not the same material as poured fondant, is commonly used to decorate wedding cakes. Although wedding cakes are traditionally made with marzipan and royal icing, fondant is increasingly common due to nut allergies as it does not require almond meal. Rolled fondant includes gelatin (or agar in vegetarian recipes) and food-grade glycerine, which keeps the sugar pliable and creates a dough-like consistency. It can also be made using powdered sugar and melted
Foam not have interconnected pores. The closed-cell foams normally have higher compressive strength due to their structures. However, closed-cell foams are also, in general, a more dense foam, require more material, and as a consequence are more expensive to produce. The closed cells can be filled with a specialized gas to provide improved insulation. The closed-cell structure foams have higher dimensional stability, low moisture absorption coefficients, and higher strength compared to open-cell-structured foams. All types of foam are widely used as core material in sandwich-structured composite materials. The earliest known engineering use of cellular solids is with wood, which in its
