Given your post history on EF and resultant rep to date, it looks like you'd know what a snotty post looks like. I apologise unreservedly for my snottiness. I do hope the helpful posts in this thread and in countless other threads on EF on this very subject, easily found if you search the forum, will help you to find baking soda in Switzerland.

Please feel free to contact me if you need any help finding brown sugar here.
