The kind of soft brown sugar available in the U.S. (C & H on the
West Coast, for example) doesn't have a straightforward equivalent in CH; you usually find crystaline, hard brown sugars instead. However, I've discovered a fairly close equivalent (produced by Tate & Lyle in G.B.) in, of all unexpected places, in *Asian* speciality stores in Germany. Might be an alternative to check out in CH, also because it involves thinking outside the box of "where are there stores selling American products?" In the process, I also discovered a Hong Kong manufacturer of Horlicks, a malt tablet/drink that has long since disappeared from the shelves of American supermarkets.
