If chestnuts are not scored, they can EXPLODE due to the pressure inside as they cook. That's easy to avoid! Making an X in the shell avoids the pressure build up. You can also make a single cut across the rounded side of the shell or cut the shell in half. We have found that cutting around the shell and then soaking the chestnut in plain water for about 30 minutes helps with the peeling process. You may then roast over an open fire (mesh baskets that can be shaken work best), in the oven or in the microwave. While there are many options for preparing chestnuts, we like this step by step instruction site, https://www.italianrecipebook.com/how-to-roast-chestnuts/
