Chestnuts roasting on an..

[Merlin5]

My neighbour and his daughter had been out collecting chestnuts and just gave me a massive load of them!

I believe they're ok for about a month in the fridge. I'm going to wash a bunch of them, score an X on the rounded side so they don't burst and roast in the oven for 20 to 30 minutes.
Anyone roasted chestnuts before?

In a wok, low heat, keep stirring...just like on the street!

That's a good idea. Do I need to score them first, and with oil in the wok? And how long until they're done?
