To determine how many shortbread biscuits Sarah can make, we first need to see how much of each ingredient is required for one biscuit. However, since the recipe for the 8 biscuits isn't provided, I will assume a standard recipe for shortbread biscuits.
Typically, a basic shortbread recipe might use the following proportions for 8 biscuits:
- Butter: 200g
- Caster sugar: 100g
- Plain flour: 300g (combining with cornflour would be clear, but let's assume a total)
- Cornflour (if necessary): the recipe could use around 75g to make up the remaining weight.
Assuming this general recipe, we can break down the total quantities Sarah has and see how many times she can use the basic proportions needed for 8 biscuits.
Total ingredients:
- Butter: 600g
- Caster sugar: 300g
- Plain flour: 1000g (1kg)
- Cornflour: 500g
Now using these quantities:
-
For butter (golden ratio per 8 biscuits: 200g)
- Max batches = 600g / 200g = 3 batches
-
For caster sugar (per 8 biscuits: 100g)
- Max batches = 300g / 100g = 3 batches
-
For plain flour (per 8 biscuits: 300g)
- Max batches = 1000g / 300g = 3.33 batches (round down to 3)
-
For cornflour (per 8 biscuits: 75g)
- Max batches = 500g / 75g = 6.67 batches (round down to 6)
Now, the limiting ingredient is butter, sugar, and plain flour which allows for 3 batches for 8 biscuits.
Thus, to find the total number of biscuits, the number of biscuits per batch (8) multiplied by the number of batches (3):
Total biscuits = 8 biscuits per batch × 3 batches = 24 biscuits.
Therefore, Sarah can make 24 shortbread biscuits.
