Ok - here is the e-mail that I sent to a well-known chocolate manufacturer:
Hello there - my 2 year old has just been diagnosed with a nut allergy. As a result I intend to do a lot more homebaking so that I can control the ingredients that go into the cakes and biscuits she eats. I was looking at your cooking chocolate and your chocolate chips and could see no information to indicate whether they are produced in a factory that also produces nuts or whether there was any danger of there being any nut traces in your products. She has been told to steer clear of ALL nuts so not just peanut.
I nearly bought your product and then thought that I would be wise to check with you directly. I would be really grateful if you could let me know.
Yours sincerely.
Below is the response I got from them:
Thank you for your e-mail and we would advise that our xx cooking chocolate and Chocolate Chips are nut free.
I can't make my mind up whether this is
a) response from someone who has obviously missed my point OR
b)(as my partner thinks) a definitive answer that should assure me that the chocolate is safe to use.
I'd love to hear what anyone else thinks!
