I think it is a north/south thing because where I was born, in Beverley, E. Yorks, everyone called it 'nugget' but once I'd had a few French lessons, I discovered it's French and should be pronounced 'noooogahhhhh' . Where I live now, in Cornwall, it's called 'noooogahhhh'.... closer to France, I suppose ;o)
..the pink and white goo is gross...my brother lives in France just over the border from Switzerland...he bought me some divine nougat, in slab form ,with whole almonds and raspberries in it....drool.... I still call it nugget though because thats what my mum always called it...
I was brought up to say nugget and assumed it was a class thing. Ermintrude mentions that gorgeous sounding nougat from Switzerland. Wonder if you can buy it on the net.
