PIP - difficulty shopping for ingredients?

Hi Thimble_fish,
Welcome to Benefits and Work.
To answer your question, I'm afraid you won't score points for not choosing food at the shop.
The test fir preparing food is the ability to cook a simple one course meal for one person, using fresh ingredients. So, in a nutshell, peeling and chopping veg, cooking a piece of meat, or making vegetarian meal, perhaps with gravy is needed Following a recipe and knowing cooking times, and testing whether cooked are all part of the test too.
Unfortunately there is caselaw about Descriptor 2, Taking Nutrition- that confirmed eating healthily as opposed to eg junk food will not score points.
Please have a look at the members guides, as there is lots of helpful information about all the descriptors. Have a look here:

PiP points are awarded on the basis of how you can do each activity, and the amount of help required.
Whilst you will not be able to score points for food shopping, if you can show that you need help to understand recipes or cooking times, or that you are unsafe in the kitchen, burning things or yourself for example, thus could allow points.
All activities have to be done safely, to an acceptable standard, repeatedly across the day as required, and within a reasonable time, meaning no more than twice the expected normal time.
Have a think about your limitations, and be brutally honest, you want to ask a friend or relative what you can't do. You can then see if you can match your limitations with descriptors. I know several people who have autism and have gained PIP, but it will of course depend on the extent of your disabilities and the problems you personally have have a read of the guides, and by all means ask further questions, which someone here will endeavour to answer.
I hope this helps.
