These were created especially for Champagne Cocktails, but we also like them with white wine or slightly sweet aperitifs, such as Lillet or sweet vermouth on the rocks. Prep and Cook Time: 1 1/2 hours. Notes: Puffs can be kept frozen for up to 2 months. Reheat, straight from the freezer, in a 375° oven until hot, about 10 to 15 minutes.
1 1/2 ounces dried porcini mushrooms
1/2 cup butter, plus more for pans
1 cup flour
1 cup shredded parmesan cheese
About 1/2 tsp. kosher salt
About 1/4 tsp. freshly ground black pepper
How to Make It
In a small bowl, pour 1 1/4 cups boiling water over porcini. Let sit 30 minutes.
Preheat oven to 425°. With a slotted spoon, transfer porcini to a cutting board, reserving mushroom liquid. Finely chop porcini and set aside.
In a medium saucepan over medium heat, melt butter in 1 cup reserved porcini-soaking liquid (if you don't have enough liquid, add water to make 1 cup). Bring to a boil, reduce heat to low, and dump in flour. Stir vigorously until mixture forms a ball that pulls away from sides of pan, about 1 minute. Remove pan from heat.
Stir in eggs, 1 at a time. Dough will separate after each addition; stir until it forms a smooth paste before adding next egg. Stir in porcini, parmesan, 1/2 tsp. salt, and 1/4 tsp. pepper.
Butter 2 baking sheets. Drop mixture by heaping tablespoonfuls 1 in. apart onto sheets. Sprinkle lightly with additional salt and pepper. Bake until puffed and brown, about 30 minutes. Cut slits in sides of puffs, turn off oven, and return puffs to oven for 10 minutes. Serve warm.
