Salt-and-Pepper Cheese Puffs (Gougères)
These easy puffs are especially good made with strongly flavored, aged white English, Irish, or Canadian cheddar. We like to use an imported sea salt with pretty, crunchy crystals, such as fleur de sel, Halen Môn, or Maldon, but any coarse sea salt will work. The puffs can be made up to 1 month ahead and frozen; cool, then freeze airtight. Reheat thawed puffs, uncovered, in a 375° oven until crisp and hot, about 5 minutes.
