2017 GCSE Food Technology Revision - Section A Design question:
How to get full marks (5/ 6 marks) for design ideas – N.B: last year needed only
ONE design idea worth TEN marks!
• recognisable sketch that fits design criteria – explain HOW your design fits
the design criteria (refer to the decorations you have chosen)
•
write the product name,
• draw two DIFFERENT products,
•
label in detail
• add measurements (what size is the product, is it a small decorated cake or a
large decorated cake? Portion sizes etc - could put weight in grams on.
• Explain HOW your product is suitable for providing sensory appeal e.g.
colour, aroma, texture, shape, variety of flavours, finishing techniques.
• Include finishing techniques and use a variety which complement each other
and fulfil what the brief has asked.

2017 GCSE Food Technology Revision - Section A Design question:
How to get full marks for the ‘how to make your product in a test kitchen’ question:
Comment on:
•
Personal hygiene – e.g. tie hair up / wash hands / wear apron
•
Kitchen hygiene – e.g. sanitise work surfaces, check equipment is clean
•
Visual checks – check ingredients are in date
•
Temperature – e.g. preheat oven to 210oC (bread products) 180oC (pasta
products)
•
Named process – e.g. slicing, dicing, sieving, rolling, whisking – aeration, grating,
baking etc.
•
Logical sequence – e.g. don’t bake your cake before it is in the tin. Do not
decorate until it has been allowed to cool after cooking
•
Quality control checks e.g. weigh ingredients using calibrated digital scales, check
homemade pasta sheets are correct size & shape, has correct amount of sauce
been added? Is cheese sauce the correct consistency? Is oven correct
temperature? Is cooking time correct? Check product is golden brown.
•
Times – e.g. sauté onions for 4 minutes, cook chicken until ‘sealed’ (5 minutes),
bake for 20 minutes
•
Kitchen safety – e.g. use colour coded chopping boards to avoid cross
contamination (definition: the transfer of bacteria from one surface to another
e.g. cutting raw chicken and then using the same unwashed knife to cut another
product or ingredient). Board colours: red (raw meat), yellow (cooked meat), blue
(fish), green (fruit / veg), brown (veg), white (dairy/bread).
•
Kitchen safety 2 – e.g. wear oven gloves. For example: ‘Place in preheated oven
180oC for 25 minutes. Remember to wear oven gloves.’ Would get you 2 – 3
marks.
•
Knowing your recipe & quantities of ingredients - try to learn FOUR relevant
recipes – basic upside down cake recipe /crème caramel/ tart tatin / marquise etc.
2017 GCSE Food Technology Revision - Section A Design
question:
How to write a design specification. Remember ‘SATSUMAS’:
• Size – e.g. it must be an individual, portion – 12cm x 8 cm.
HOWEVER: If you just copy the design criteria from the question
you will NOT get a mark
• Appearance – Describe the appearance of the decorations
using sensory vocabulary.
• Taste / Texture – cake must be light, fluffy with consistent air
bubbles and display work should be consistent
• Shape – What shape will the product be? How will this shape
be achieved? Tin or cutters or piping?
• Unit cost – e.g. my product must cost no more than £1.50 per
portion
• Use by date – e.g. my product must have a 3 day shelf life as it
contains high risk foods.
• Materials – e.g. my product must be made using seasonal,
locally sourced fruit, free range eggs , seasonal fruit, unsalted
British butter, Fairtrade cocoa, chocolate and sugar etc.
• Mass (weight) – how much should it weigh? Remember to
consider nutritional needs of the target market & ‘sensible’
portion sizes.
• Age (target group) – e.g. my product must be suitable for… give
an age range, gender and situation – make sure this agrees with
the design brief
• Suitability for manufacture – is this a “one off product” or
could it be batch produced? If it is smaller could it be mass
produced? What are the positives and negatives of each
production type?
• Storage – e.g. it must be stored chilled at 0 - 4 oC

Description:
Remember! Saturated fat contains more cholesterol, which has been
linked to an increased risk of heart disease. They should therefore
be used more sparingly in cooking.
The Functions of Fat
Function
Description
Fat coats the flour particles, preventing the flour
absorbing the water. Preventing the water absorption
stops the gluten developing. If the gluten cannot develop
the mixture is shortened giving a crumbly, melt in the
mouth texture.

High risk foods - Those most likely to encourage bacterial
growth. e.g. cooked meat, cooked poultry, fish, dairy foods.
Image/Mood board - A display of pictures and drawings to give
ideas about a target group or a range of products.
