Re the Environmental Health people.
I've been going about a year, and sell my cupcakes at Farmers Markets. When I registered the EHO man came round, had a very quick nose around the kitchen, and said (as everyone else has mentioned) that as I'm very low risk (even with two kids, two cats and a dog) my kitchen would be fine. He said I would be visited to be inspected properly at some point, but around here they CANNNOT just turn up on your doorstep, they have to give 24hrs notice.
My market stall was inspected just before Christmas and the EHO there said basically the same, as long as you have plenty of hand washing facilities, make sure you cakes are all up to temp when cooked, and do not have any cross contamination from stuff you'll be fine!!!!
I've got the Safer Business package, which I complete (usually after the event!) for when I bake, decorate, and do a market, which I basically just sign to say that I did my open and close checks and nothing else happened. The EHO was happy that that was enough.
Basically, what I'm saying is the paperwork although looks daunting, it isn't much more than common sense, and a lot of it doesn't apply (unless you are using fresh cream!)
Time to be nosey, how do you sell your cupcakes/cakes? Do you advertise? What are your fav suppliers in the uk (have to ask, couldn't bare it if I was missing out on something
