I think I will need to try just bbq. I saw them sold on street corners in Budapest and Sofia in winter, usually on charcoal or gas. I like charcoal. 

Boiled they are nice but I prefer a bit of crunch. Horse chestnuts are an Asian staple and I like the texture of them.

I can't really eat a lot though. But it reminds me I should eat more from the batch I have in the fridge.

Overall I think they are a nice side dish. They grow everywhere in the temperate zone. I remember walking past gazillions of them along the main street of some town in central-eastern Italy also.

Idk why I confused them with hazelnuts but they are about the same colour.
