Thursday

 

WALT: adapt recipes.  THIS WILL BE OUR ZOOM LESSON FOR THIS WEEK.

 

When we look at recipes, the amount of ingredients we use needs to be dependant on the number of people for whom we want to make.  A lot of recipes are usually for 4 or 6 people however what happens if you want to make something for a different number of people?  How can we change the amount of ingredients to make sure the food still tastes nice and the right amount of ingredients are used?  Look at the example below:

 

Jake is making scones.  Here is a list of ingredients he needs to make 8 scones.

200g flour

30g caster sugar

50g butter

140ml milk

1 egg

How much of each ingredient would he need to make 16 scones? How can we work this out?

 

Well, if we know the amount of ingredients for 8 people, what can we do to work it out for 16 people?  We know that 16 is 2 lots of 8, or double 8, so because we know that, we can double each of the ingredients that are needed for 8 people.  Therefore, if 200g of flour is needed for 8 people, then 400g of flour will be needed for 16 people.

How many eggs would we need?

 

Your task today, after our zoom lesson, will be to use this information to work out the right amount of ingredients needed for the following number of scones.

 

Challenge 1:

a) 4 scones 

b) 24 scones

 

Challenge 2:

a) 40 scones

b) 12 scones

 

Challenge 3:

a) 6 scones

b) 28 scones

 

There is also an extension exercise if you would like to challenge yourself further.  Choose any recipe.
