Though you need only 10 cloaks to top the pears, these melt-in-your-mouth wafers are so delicious, your guests will clamor for seconds. If you don't have time to turn the wafers into cloaks, simply make flat tuiles and serve them on the side.
Cooks' note:
Onions can be fried 6 hours ahead and kept, uncovered, at room temperature.
