spoon the mixture into the muffin cases until two thirds and bake in the oven for 30 minutes, or until the sponge bounces back when touched
Leave the muffins to cool slightly in the tray before moving them to a cooling rack
Step 5: The Science Behind It
They use baking powder which is a blend of acid and alkalis. These create carbon dioxide bubbles when liquid and heat are added.
Most baking powders are double acting, that is they produce an initial set of gas bubbles upon mixing and then a second set during the baking process.
When using baking powder, add this ingriedient last as it will begin to create CO2 as soon as it comes into contact with moisture
