2014 GCSE Food Technology Revision - Section A Design question:

How to get full marks (5/ 6 marks) for design ideas – • 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.

2014 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 fresh pasta recipe /pasta dishes / white sauce / tomato sauce etc.

2014 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.

• 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 FatFunction 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.

Extend shelf-life

Required to add air into food. Eg. When fat is creamed with sugar to helps traps air
