Bronze Proof

Can I do cookery for my Bronze DofE?
I have to do a Skill for my Skills section of Bronze DofE, and I was wondering, could I do cooking for it, and could I get my mum to sign it for me?
I cook a lot anyway, but not every week. However, I would be more than happy to spend an hour + in the kitchen cooking something new every week.
Additional details: My Bronze DofE won’t be completed in a little booklet like before, this time we are on the internet (according to my school) so in order to show that I have been cooking food every week, I could take a picture of it and upload it onto the site couldn’t I? That way, I have proof that I have been doing the cooking every week.
Thanks in advance.
you can’t have a family member sign it, but you can have a family friend sign.. but i think you could.. check the website. like i did swimmingfor the sport, i did it loads anyway, i just got my godmother to sign.
i think it has to be a skill you improve, and cooking would if you did it that often.
