Olive oil is a perfect (and extra-flavorful) nondairy alternative to butter for these tuiles, which defy logic by being both gossamer (potato starch gives them a melt-in-your-mouth quality) and sublimely crisp.
Cooks' notes:
·If cookies become too crisp to curl, return to oven to soften 1 minute.
·Cookies keep in an airtight container at room temperature 1 week.
