Assessment Task 2 (10/10) - Compiling the final image
After I had taken all the photographs, I imported them into Photoshop and put them together.
The brown set (hi-res) represents the roles of each of the ingredients. From left to right:
STRUCTURE - Flour and eggs assist in creating the structure for the cake, which I represented by forming a "brick" wall out of the two ingredients.
LAYERING - The layers surrounding air pockets in the cake are formed by the sugar, fat and egg. Sugar and butter form the initial bubbles, which are then further surrounded by a thin layer of egg. In the middle of the sugar pile I've placed a small square sheet of bubble wrap to signify the air pockets.
AIR POCKETS - Baking powder, sugar, fat and egg all play a role in the formation and expansion of the air pockets. The balloons came about from divergently thinking about air pockets.
GLUTEN FORMATION - Fat and sugar prevent the formation of too much gluten in the cake, resulting in the soft, crumbly cake texture.
MOISTNESS - Sugar and fat contribute to the moistness in a cake, while egg provides the majority of the liquid in a cake batter.
SWEETNESS - Sugar is the source of sweetness in a cake.
The red set (hi-res) represents the chemistry that occurs during the baking process. I have used red as the backdrop to reflect the heat in the oven. From left to right:
When the cake first enters the oven, the air pockets are small and not yet inflated.
Bubble expansion begins and causes the cake to rise.
Thermal expansion, water vapour and carbon dioxide all assist in the expansion of the air pockets and hence the rising of the cake. At this point, the egg begins to coagulate which causes the cake to solidify.
At the end of the baking process, Maillard reactions occur which causes the cake to brown and crust (and hence the brown/ orange paper).
To combine the two sets together, I placed the on top of each other and applied a mask of concentric circles to the top layer. By doing this, only sections of the two sets are visible. I wanted to demonstrate the correlation between the two processes - that it requires both the ingredients and the science to form the cake. The idea behind the concentric circles was taken from Russell van Kraayenburg's Season Produce posters. Circles also embody the air pockets and the layering of fat and sugar around the air bubbles.
