Query: So delicious

This very crispy sugar wafer is perfect with ice cream, or with coffee or tea. It's got a lovely burnt marshmallow flavor. I really like these- they seem to harmonize with anything. I'm allergic to GMo cornstarch, so it is hard for me to find cookies I can eat. This one is lovely, and it's safe for me to eat.
