Nougat, it appears, is from Provence. Technically, Drome Provencale, but close.
The French claim that nougat traces back to a Greek walnut confection known as nux gatum or mougo that was originally made using walnuts. In the 17th century, Olivier of Serres planted almond trees close to Montelimar. It is thought that the almonds replaced the walnuts in the Greek recipe and evolved into nougat. Today, Montelimar is known mostly for nougat. The first commercial factory opened in the late 18th century and now this city has 14 nougat manufacturers producing this wonderful confection.
Nougat is made by whipping egg whites until they are light and frothy. Sugar or honey syrup is added to stabilize the foam and creating a frappe; almonds (or other a list of other nuts such as hazelnuts, pistachios, or walnuts) are added. And therein lies the problem.
For those of you who enjoy amusingly bad translations, a history of nougat is provided by one Montelimar nougat manufacturer, Gerbe d'Or: "historically, the starting of the nougat goes back to several centuries."
