Science Lesson 6 (Chocolate rice crispy cake)

A lot of cooking involves chemistry and is essentially a series of chemical reactions. Knowing about this kitchen chemistry can help you to understand much more about what’s happening – and why your recipes sometimes go wrong!

Cooking and chemical changes: new substances are made, the process is irreversible and an energy change occurs. For example, bread turns brown as it is toasted. Sugars in the bread break down to form carbon. This change needs heat energy from the toaster, and it cannot be reversed.

This time we looked at how the ingredients change through the recipe.
