At this time of year, store shelves are full of torrone and its varieties. I spotted coffee, cranberry and pistachio versions on my last trip - I also noted the hefty price tag. Make your own, fresh, giant batch of soft, chewy (or firm!) nougat, and flavor it however you like.

Marcona almonds and honey have been used to flavor this nougat for centuries.
Admittedly, this version of the 3 Musketeers isn't quite as fluffy as the original, but it does have the mild chocolate flavor your remember. Use milk chocolate for a classic 3 Musketeers bar, or dark chocolate for a "Midnight" edition.
