The test of capability is whether you can do something 'reliably'. That means:
- To an acceptable standard
- Safely
- Repeatedly
- In a reasonable time frame
www.mypipassessment.co.uk/updates/what-are-the-reliability-criteria-that-are-used-during-the-pip-consultation/#:~:text=For%20the%20purpose%20of%20PIP,be%20acceptable%20to%20most%20people.
For cooking, a 'meal' is a simple meal made from fresh ingredients. For example, an omelette with cheese and tomatoes.
For PIP 'feeling unsafe' is not enough to score. To score under 'safety', there has to be a realistic prospect that you may come to harm by doing the activity, even with the use of aids. For example, if you said 'I get wobbly when I stand at the worktop to chop vegetables, so I might cut myself with the knife', it would be reasonable to expect that you would use a stool to make it safer. If you can lift a pan of boiling water but not carry it across the kitchen to the sink, it would be reasonable to expect you to use another pan to drain the water into, then wait for it to cool before pouring it away, so that you are only potentially spilling cold water, etc.
Safety comes into play with things like the ability to check if meat is sufficiently cooked, whether you would recognise that food has turned bad in the fridge, etc.
'Repeatedly' for cooking means being able to prepare your meals for the day. So if you can make breakfast, but the effort of doing it means that for the rest of the day you don't eat because you're so exhausted by the effort it took, then you can't 'make breakfast'.
'To an acceptable standard' - is the food edible once you've cooked it? If someone can only cook one thing at a time, so everything goes cold while the next thing is cooked, that wouldn't be 'an acceptable standard'.
'In a reasonable time frame' - it should take no more than twice the amount of time that an average person would take to make the same thing.
Have a look again at what you wrote on your form, and think about your needs. If you feel that you are genuinely at risk of harm when you cook (rather than preferring your DH to cook because you feel unsafe) you will need to explain why your aids don't make it safe enough. Then take all the other factors one by one, and explain why you should score points.
The criteria can be very strict. DD2 gets enhanced care and mobility. However, despite having a severe expressive language disorder and a severe social communication disorder (both properly diagnosed and in weekly therapy for) and Autism that affects her ability to understand and process information, she scored 0 points for 'understanding complex information' because 'complex information' means 'More than one sentence written in standard text size in their native language'.
You really do need to understand what the terms mean for each activity - each one will have a specific definition which the criteria are applied to.
