Teuscher claims to have invented the champagne truffles... and aren't there some truffles in the background? Heh. All of this is pretty weak reasoning I suppose.
Teuscher's claim is not supported by real facts, although it does claim to have invented the "champagne truffle" (and may have done so (I don't know). The wife of the founder of Teuscher is currently alive at 92 years old, so it is highly unlikely that her husband the now-deceased Dolf Teuscher was old enough to invent chocolate truffles before 1895. Here is some information on chocolate truffles, particularly the Swiss kind:
The chocolate truffle was first created by M. Dufour in Chambéry, France in December 1895. They reached a wider public with the establishment of the Prestat chocolate shop in London by Antoine Dufour in 1902, which still sells 'Napoleon III' truffles to the original recipe. There are now three main types of chocolate truffles: American, European, and Russia:
The "American truffle" is a half-egg shaped chocolate-coated truffle, a mixture of dark or milk chocolates with butterfat
A Canadian variation of the American truffle, known as the Harvey truffle, includes the addition of graham cracker crumbs and peanut butter.
The "European truffle" is made with syrup and a base made up of cocoa powder, milk powder, fats, and other such ingredients to create an oil-in-water type emulsion.
The "Swiss truffle" is made by combining melted chocolate into a boiling mixture of dairy cream and butter, which is poured into molds to set before sprinkling with cocoa powder. Unlike the previous two kinds of truffles, these have a very short shelf-life and must be consumed within a few days of making.
There are hundreds of different variations of recipes for making truffles.
