Porcini Popovers

Directions

1. 1.

   Grind porcini to a powder in an electric coffee/spice grinder or a blender (you’ll have about 1/4 cup). Whisk together porcini powder, flour, salt, eggs, milk , and melted butter until smooth, then let rest, chilled, 1 hour.

2. 2.

   Preheat oven to 400°F with rack in middle. Butter popover cups. Cut remaining 2 Tbsp butter into 12 pieces.

3. 3.

   Heat popover pans in oven 2 minutes. Remove from oven and add a piece of butter to each cup. Return to oven and heat until butter is bubbling, about 1 minute. Divide batter among cups (a scant 1/2 cup each) and bake until puffed and golden-brown, 30 to 35 minutes.

4. 4.

   Pierce top of each popover with a sharp knife to release steam, then continue to bake until deep golden-brown, 5 to 10 minutes more. Serve immediately.

5. 5.

   Popovers can be baked 4 hours ahead. Remove from pans and reheat on a baking sheet in a 350°F oven until hot and crisp.
