Nina's cooking from school!

I went out yesterday especially to get ingredients for Nina as she was cooking Bakewell tart at school. Yum.... I thought. When I got home from work this is what I found in a bag on the table!!! Not sure where the teacher was during the session, but I think a little guidance on cooking times may have been needed! I've put it back in the oven, but fear it may be too late :(
UPDATE I've burned it now and it looks very unappetising!
