Meringue Mushrooms

Langkah-langkah

1. Preheat the oven to 225°F (107°C) and line a baking sheet with parchment paper.

2. In the bowl of an electric mixer fitted with the whisk attachment, beat the egg whites and cream of tartar on medium speed until soft peaks form, about 2 minutes Gradually add the sugar, one tablespoon at a time, then increase to high speed and beat until stiff, glossy peaks form and the sugar is fully dissolved, about 7 to 10 minutes (rub a little between your fingers—it shouldn’t feel gritty). You'll know it's ready when you lift the whisk out of the bowl and the meringue holds a firm peak that curls just slightly over.

3. Transfer the meringue to a piping bag fitted with a ½-in (13-mm) round tip. On the prepared baking sheet, pipe 12 mushroom caps and 12 stems, plus one or two extras of each in case any crack or don’t match up perfectly.

4. To make the caps, hold the piping bag perpendicular to the pan and pipe small rounds about 1 to 1½ in (2.5 to 4 cm) wide, stopping just before lifting the bag to avoid forming peaks.

5. For the stems, pipe small upright mounds about 1 inch (2.5 cm) tall, applying a little more pressure at the base and easing up as you lift to create a gentle taper—narrower at the top, wider at the bottom. Don’t worry about making them perfect; once the mushrooms are assembled, you won’t notice minor differences, and a little variation actually makes them look more natural.

6. If any caps have little points, smooth them with a damp fingertip. (Don’t worry about the stems since you’ll trim them later.)

7. Lightly dust the caps with cocoa powder for a natural look. Bake until dry and crisp but not browned, about 1½ hours. Turn off the oven, prop the door open slightly, and let the meringues cool completely inside, 1 to 2 hours.

8. Use a paring knife to gently cut off the pointed tip of each stem so they’ll be flat. Place the chopped chocolate in a small microwave-safe bowl and heat in 20-second bursts, stirring after each, until just melted and smooth (stop before it’s fully melted and let the residual heat finish the job so it doesn’t scorch).

9. Using a small offset spatula or the back of a spoon, spread a thin layer of melted chocolate over the entire underside of each cap—this gives them a realistic, dark “gill” look. Then, while the chocolate is still soft, gently press a stem into the center of each cap. Place the assembled mushrooms upside down on the parchment-lined baking sheet (caps resting flat, stems pointing up). They won’t stand upright until the chocolate sets, so this helps keep everything in place. Let them sit at room temperature or in the fridge until firm, 10 to 15 minutes.
