Do you have trouble opening those chestnut shells? No problem here is what you do. Use the pointed end of the bottle opener that you have. You pierce the tops and the bottoms of them and then just boil them and you will have chestnuts without the shells. Just boil it for 10 minute and then you will be all set. My grandmother told me this tip and she is full of great stuff. I should really talk to her more because she is amazing in the kitchen!
