Ratios: The Maths of Baking

The video tutorial explains how to use ratios to adjust the size of a sponge cake recipe. It begins with a basic recipe and demonstrates how to simplify ingredient ratios. The tutorial further explains how these ratios can be used to scale the recipe up or down, ensuring the proportions remain consistent. By understanding and applying these ratios, one can make cakes of any desired size.

What is the main purpose of using ratios in a sponge cake recipe?

• To easily scale the recipe up or down

• To maintain the texture of the cake

• To make the cake rise properly

• To ensure the cake tastes sweet

How can the sugar to flour ratio of 200 grams each be simplified?

What is the simplified ratio of eggs to milk when using 4 eggs and 30 milliliters of milk?

• 2 to 15

• 1 to 7.5

• 1 to 15

• 4 to 30

If you want to make a cake twice the size of the original recipe, what should you do?

• Add more eggs

• Add more sugar

• Use half the amount of each ingredient

• Double the amount of each ingredient

What happens to the ratios if you multiply all ingredients by the same factor?

• The cake becomes denser

• The ratios remain the same

• The cake becomes lighter

• The ratios change
