I'm pretty sure you will have to roast your own chestnuts. But as long as you carefully score them with an X mark they will not explode. Also, inspect them at the store for worm holes before buying. I've often found that most of a supermarket batch are worm-ridden. Right now, I'm thinking of doing some chestnuts on my gas grill. Any of you bbq mavens out there have any ideas about the optimal heat level? In the past, I've done them in my fireplace, nestled among the coals.
Another option is just to locate some Marrons Glacees (at Treasure Island in the refrigerator section over the holidays and at Fox & Obel, no doubt) and call it dessert.
Man : I can't understand how a poet like you can eat that stuff.
