Marshmallows. [from the wiki]
A marshmallow is a sugar-based
confection that, in its modern form, typically consists of sugar, water and gelatin which is whipped to a spongy consistency, molded into small cylindrical pieces, and coated with corn starch.
The word marshmallow stems from the mallow plant (Althaea officinalis) that is a genus of an herb native to parts of Europe, North Africa, and Asia. The word "marsh" is used because the mallow plant grows in marshes and other damp areas. The plant itself has a fleshy stem, leaves, and a flower that has five white petals. There is no exact date as to when marshmallows were invented, but their history goes back as early as 2000 B.C. Ancient Egyptians were said to be the first to make marshmallows, and it was considered a privilege to be able to partake in its consumption. It was strictly reserved for gods and royalty, who took the root of the plant and used it as a medicinal to soothe coughs and sore throats, and heal wounds. The first marshmallows were prepared by boiling pieces of root pulp with sugar until it thickened. Once thickened, the mixture was strained, cooled, and then used as intended.
As to the term candy bar used in the states and some parts of the canadas - that term was at one time reserved for any bar confection not made from chocolate but might have a coating but today even the coatings are not really chocolate to begin with. So in most common usage Chocolate Bar is reserved for bars of mostly chocolate or a close facsimile thereof - ie what you see in most grocery store candy isles and beside checkout counters. Usually cheap analogues like Hershey or imports from Eastern Europe to overpriced flat designer slabs touting their cocoa content on their labels.
My chocolate preferences is something like Schwarze Herren Schokolade that I always bugged relatives to bring over with them from Germany or Mozartkugel which, thanks to Ferraro opening shops nearby, I can be tempted on a daily basis with FRESH chocolates.
I personally favor as a candy McIntosh Toffee or Marzipan, if I could find either, as great examples of a candy bar with Eatmore on my list, which even I don't know why I like it.
