Craquelin-Topped Cream Puffs

Step 1

To make the craquelin: Pulse the butter, sugar and salt in a food processor until just blended. Add the flour, and pulse until you have moist curds; pulse in the vanilla. Scrape the dough out onto the counter, and pull it together into a ball. Divide in half, shape each half into a disk and roll out each piece between parchment paper until it’s about 1/8 to 1/16 inch thick. Freeze for at least 1 hour, and then cut into 1 3/4-to-2-inch-diameter rounds. Freeze until needed (always use frozen).

Step 2

Preheat the oven to Line 2 baking sheets with parchment paper. Have a small (2-teaspoon capacity) cookie scoop, spoon or a piping bag at hand.

Step 3

To make the puffs: Bring the milk, water, butter, sugar and salt just to a boil in a medium pan. Reduce the heat to low, add the flour all at once and start stirring like mad with a flexible spatula. Stir and mash the dough until it comes together and leaves a film on the bottom of the pan. Keep cooking and stirring nonstop for another 3 minutes to dry but not color it. Scrape the dough into the bowl of a mixer fitted with the paddle attachment (or work with a hand mixer). Beat the dough for 2 minutes to cool it down a bit. Combine the eggs and white, stir with a fork to break them up and then add to the dough in three additions, beating on medium speed. Beat until the dough is satiny and runs off the beater smoothly.

Step 4

Scoop, spoon or pipe puffs that are about 1 1/2 inches in diameter, leaving about 2 inches between each puff. (At this point, you can freeze them and then, when they are solid, pack them in an airtight container. When you’re ready to bake, arrange the frozen puffs on a lined baking sheet and keep them on the counter while you preheat the oven.) Place a frozen round of craquelin on each puff.

Step 5

Bake for 30 to 35 minutes, rotating the baking sheets if needed, or until the tops are golden brown and crackled. The puffs will feel firm when gently squeezed and sound hollow when tapped on the bottom. Transfer them to racks, and cool to room temperature.
