"Today we made sticky chocolate drop cakes using the melting method. We have been learning about how raising agents work in class - today we used both natural and chemical raising agents to ensure they brownies rose in the oven! We introduced air into the mixture by sieving the flour for our natural raising agent. We also used a chemical raising agent - baking powder (acid + base) which is in self-raising flour. When mixed with a liquid, the chemical reaction makes the brownies rise in the oven. We really enjoyed making and eating these scrumptious brownies!
