So how did we go about baking New Zealand's top iPhone cooking app?

Here's our secret recipe:

Ingredients

• Picture of an iPhone with a blank screen
• Pictures of buttons, dials, objects and icons featuring different iPhone and recipe functions
• A list of possible ingredients
• A list of possible cooking styles
• A sample recipe 
• A dozen people from different walks of life (who use iPhones)
• A list of questions with tasks

Equipment

• Printer
• Stanley knife
• Pen
• Camera
• A table

Steps

1. Print the picture of the iPhone, buttons, dials and icons to 140gsm paper.
2. Cut out the pictures with the Stanley knife then lay them on the table.
3. Next, invite one of the people and show them the cut-outs.
4. Now, ask them a question(e.g."This is the start screen. What would be the six most useful options on this screen for you?").
5. Observe and note what they do with the cut outs.
6. Move onto the next question and repeat steps 4 to 5. When all the tasks have been completed move onto step 7.
7. Move onto the next person and repeat steps 3 to 6. When all the people have finished move onto step 8.
8. Taking your observations and their feedback, mix-in with your iPhone app contents.
9. Leave to rise.
10. Knead and shape into desired design.
11. Put into a programmable oven and bake until half cooked.
12. While still gooey get the people back to taste-test.
13. If they don't like it then repeat steps 8 to 12.
14. If the people are satisfied then put back into the programmable oven and bake until fully developed.
15. While still warm place on the iTunes shelf.
16.  Serve with iPhone or iPad.
17. Share and enjoy!
