That Cake Decoration Though…
How come cake engineering is a thing? Well, of course, aluminum foil is a good supplement for a pastry bag. When there is no pastry bag for decorating a cake, aluminum foil can be curved into a tube, as a column or as a wall, is a matter of physics.
The tube is then filled with frosting and it works just as good! So whenever you want to make a themed cake for kids or even a fancy party cake, aluminum foil is your best friend for cake architecture!
