Prepare the pate a choux: Place the water, salt, granulated sugar, and butter in a 4-quart heavy-bottomed saucepan, set it over medium-high heat, and bring to a boil. The butter should be completely melted by the time the mixture boils. Remove the saucepan from the heat. Add the bread flour all at once and incorporate it thoroughly with a wooden spoon.

Return the saucepan to the stove and cook over medium heat for about 3 minutes to dry out the paste. As it cooks, push the paste from side to side with the wooden spoon. Turn it onto itself to allow every side to touch the bottom of the saucepan, which helps it dry. Keep the paste moving, or it will burn. The paste will dry out and leave a thin film on the bottom of the saucepan.

Remove the saucepan from the heat and transfer the paste to a large mixing bowl. Mix with an electric mixer set on low speed for about 2 minutes to release some of the steam. Continue to mix and slowly add the eggs 1 at a time, incorporating well after each addition. After each egg is added, the paste will become loose and look separated. Once each egg is well incorporated, the paste will become smooth again. The number of eggs used will vary depending on the size of the eggs and how well the pate a choux is dried. The drier it is, the more eggs you will need. After you have added 2 eggs, check the consistency by scooping a large amount of the paste onto a wooden spoon. Hold the spoon horizontally about 1foot above the bowl and watch as the batter falls from the spoon back into the bowl. If it is pale yellow, smooth, moist, slightly elastic, sticky, and takes 5 to 7 seconds to fall into the bowl, it is ready. If it appears rough, dry, and falls into the bowl in 1 big ball, it needs more eggs. Add another egg and check the consistency again after it is well incorporated.

To make the caramel: Place the sugar, corn syrup and water in a 1-quart heavy-bottomed saucepan and cook over medium-high heat until light golden brown. Pour the caramel into a heatproof bowl to hold the temperature of the sugar. Put a towel under the bowl to keep it from tipping and to protect your hands from the heat of the glass.

Assemble the centerpiece: The caramel acts as glue. Dip the bottom of the first large S into the caramel and stick it to the largest base going from the out side rim of the circle, towards the center of the circle. In other words, the base supports should almost meet each other in the center of the circle. This creates a structure for the next layer to rest on. You will have to hold each S support in place in order for the caramel to harden and actually stick, keeping the S shape in the right position. Repeat using the other 4 pieces, spacing them evenly. Dip the bottom of the first small S into the caramel and stick it to the medium-sized base. Repeat using the other pieces, again spacing them evenly. Place the medium size base on the large S supports. Top the small S supports with the smallest base. You will have a 3 tiered structure.

To assemble the butterflies: using the caramel as glue, connect 2 sets of the wings together. Do this along length of the wings. Adjust the wings to sit at a slight angle, as though the wings are in mid-flight. Do this with all 10 wing sets, creating 5 total butterflies. Using a paring knife dipped in the caramel to spread it might be easier than dipping the wings or bodies in the bowl of caramel. You may need to prop the wings up while they harden. You can do so using 2 rolling pins or 2 thick books lying with about 2 inches between them. The space between them is where the glued center juncture will rest on the work surface and you will be able let the wings harden on a slight angle; this way you will not have to hold them in place until they harden. Using more caramel, glue the bodies to the area where you glued the wings together. Place the fatter end of the body at the top section where the wings are joined. Glue the antenna to the fatter part of the bodies. If at some point during the gluing process the caramel has become to stiff to use; place the caramel in the microwave oven at 30-second intervals, until it loosens up for you to use it again. Once the butterflies have been assembled and the caramel has hardened, you can then glue them wherever you like on the 3-tiered centerpiece.

Place the centerpiece on a large tray. Display the Bomboloni and the Cloud Puffs around the centerpiece. Voila!
