Lemon & Passion-fruit Cake
LEAVENING:
INGREDIENTS: (BETWEEN 2)
METHOD:
- DEFINITION OF LEAVENING: Leavening is the process of incorporating one or more gases into a product. It can be done by:
The proteins listed in this recipe are carbohydrates, milk (gluten), eggs and flour. The egg goes through denaturation and coagulation, as it is beaten and then cooked. A colloidal dispersion is involved, it occurs during the beating of the sugar and butter; it is a solid and gas system. When acids, alkali and water meet, it produces carbon dioxide. Other products that use leavening include:

EQUIPMENT:
The leavening agent in this recipe is the self-raising flour. Other agents include baking soda, baking powder, steam, air and yeast.
Leaving agents rely on incorporating gases by methods that involve actions such as beating or generating carbon dioxide by incorporating yeast or baking powder. Leavening agents use the scientific principle that when a gas is heated, it will expand and rise. As a result, baked products rise. Once cooked, the cake remains in a standing form due to the coagulation. The eggs hold the gas inside during the cook, when the gas escapes the air bubbles remain. The physical reactions are changes in texture- as the gas is incorporated into the cake- flavour and colour. It turns from a sludgy light cream colour, to a firm, stable browned cake with form.

Tips & Evaluation
It is important to thoroughly read through the recipe to be able to achieve the imagined flavour. Without going through the leavening process, the cake would be flat, and rubbery in texture. It would be distasteful and off-putting in appearance, failing to be the recipe's end produce.
Leavening makes the bread light and soft to consume. The lemon and passion-fruit flavours seep into the cake as it cooks, so it's important to give it the right amount of time in the oven. Make sure to fold in the flour, and not to knead it. The texture after it has been cooked would not be light and fluffy, and instead be more compact- like cookie dough.
