A legendary
peppermint patty,
AFAIK the first in the market. It can be described as a
chocolate sandwich with two thin leaves of
dark chocolate and a
creme de menthe filling inbetween.
These gentle pieces of art are wrapped in thin brown envelopes that resemble tea bags and then placed in a package that is much like a blackish-green cardbox of a 25 pack Twinings tea.
Although all these give you the idea that this is a British product it is actually made by Nestle in Switzerland.
