I like the idea of being a small business, and supporting local small businesses as well (hence, buying local, free-range eggs, local fruits, etc.) For some customers, that is important, and that's the market I enjoy working with. That's why they buy from me, and I don't have to worry about competing with Walmart -- they don't shop there anyway!
But, to get back to the original post, again, under NYS law, we have to provide an ingredient list -- and every single one of the "numbered" food colorings must be declared -- so box yellow, box red velvet -- and ALL the commercial preservatives -- one would have to declare those components. When I use spices, I can write "organic spices" (hence, KFC doesn't have to disclose their secret spices).
I am sure the OP (also NYS) is doing this...it would be interesting to know if other states require this as well. I can't just provide it if asked, I have to attach it to the box.
What do box mix users do in terms of disclosing ingredients? I was just wondering what your state/country requires....?
