Re: Chest nuts aka Singhara
First of all you need to get the shell/skin off. Pierce it down the flat part of the shell and let it cook for about 5 minutes in boiling water. When it starts to cool down a little bit (dont wait too long it gets harder to peel them then) you could peel and drain them. They're already half cooked. After that you could do whatever you want with them... boil them, steam them, , bake.. etc etc.
If you want to roast them, slash tehm horizontally, place in the oven on a baking tray at 400F for 15-20 mins flipping them over from time to time.
