Ingredients

For ingredients and detailed instructions, refer to the recipe card below.

First, let’s chat about ingredients. You just need four simple ingredients:

• Egg whites - large egg whites at room temperature.
• Icing sugar - the same as powdered and confectioners' sugar.
• Unsweetened cocoa powder
• Dark chocolate - melted dark chocolate (read how to melt chocolate) or replace it with milk, white chocolate, or chocolate chips.

Dark chocolate brings a more realistic look to meringue mushrooms under the cap. You can also use royal icing or buttercreaminstead of melted chocolate to "glue" meringue caps and stems.

How to make meringue mushrooms step-by-step

Preheat the oven to 210°F (100°C). Line a baking sheet with parchment paper.

Step 1. To make Swiss meringue,place egg whites in the clean bowl of astand mixeror a large metal bowl.

Step 2. Add powdered (icing) sugar and whip egg whites with a hand whisk a few times. Put the bowl over the bain-marie or water bath and beat egg whites with a whiskuntil foamy.

Step 3. When the meringue mixture is hot, remove the bowl from the heat and beat it with a stand or electric mixer until it cools completely. The meringue will have a glossy appearance with stiff peaks. Use it right away.

Step 4. Transfer meringue to a large piping bagwith around piping tip of ½" (12 mm).Pipe 4 meringue dots in the corners of the prepared baking sheet and place parchment paper. It will fix the paper during pipping and baking.

For the caps of the mushrooms, keep holding the piping bag upright to the baking sheet and smoothly squeeze the bag. Push the meringue into a plain round shape (photo 1).

Once the perfect shape is obtained, stop squeezing and slowly remove the bag off to the side to avoid creating a peak on top. If needed, use a wet fingertip to flatten the spike of the meringue dome.

Step 5. Hold the pastry bag upright on the baking sheet to pipe the meringue stems. Start piping gently, forming a stem's base, then lift the bag while squeezing. Make sure to make the pointed end by pulling up the bag (photo 2). Caps and stems should be placed 1 inch (2.5 cm) apart.

Pro tip: The size of mushroom caps and the height of stems may vary: while the caps may average 1 to 2 inch (2.5 cm to 5 cm) rounds and about 1 inch (2.5 cm) high, the stems may get about 1 inch (2.5 cm) tall.

Step 6. Sprinkle mushroom caps withcocoa powder.

Step 7. Bake caps and stems for 1 hour. Once the meringues are ready, let them cool and detach fromparchment paper.

Step 8. To assemble meringue mushrooms, carefully select and arrange the caps and stems to achieve the most visually appealing size and shape combinations. Melt chocolate according to any of the ways described in the chocolate mousse recipe.

Then, use one of the provided methods for assembly.

• Make a small hole on the bottom of each cap with the tip of a small paring knife. Fill the hole and the top of the stems with a little melted dark chocolate. Insert the stems into the hole under the caps. Place the mushrooms upside down and refrigerate to allow the chocolate to set.

• Slightly trim the tops of the mushroom stems evenly using a serrated knife. Using a small offset spatula, coat the bottom of the cap with melted chocolate (photo 3). Dip the tip of a mushroom stem into the chocolate and twist it gently to attach the cap and stem together (photo 4). Place the assembled mushroom upside down on a wire rack lined with parchment and allow the chocolate to set.

Pro tip: Don't worry about slightly crooked stems: they will appear perfect when flipped over. However, adjust any completely fallen stems.

Step 9. Sprinkle a little cocoa powder on the upright meringue mushrooms to give them a freshly emerged look from a soft earth patch.

Expert Tips

1. Make sure egg whites are at room temperature.
2. Pipe different rounds and lengths of mushroom caps and stems.
3. Make a few extra stemssince some of them may fall during baking.
4. Once meringue caps and stems are baked, keep the oven door slightly ajarto allow the meringues to cool, although it is optional.
5. Keep the baked caps and stems uncovered for a few days at room temperaturebefore you assemble the mushrooms.
6. Store ready meringue mushrooms in an airtight container for a few weeks.
7. While presenting a Bûche de Noël, decorate a serving platter with meringue mushrooms, fixing them with melted chocolate. It will prevent them from breaking when they accidentally fall while serving the log to a holiday table.

Storing and freezing

Store the cooled meringue mushrooms in an air-tight container, preferablya tin box, at room temperature for up to two weeks.

Can you freeze meringue mushrooms? To freeze meringue mushrooms, place them on parchment flat and freeze them. After one hour, transfer meringues to an airtight container and keep them in the freezer for several weeks.

To thaw, bring them to room temperature for about an hour.

Recipe variations

• Replace cocoa powder with sifted freeze-dried strawberry powder on meringue mushroom caps.

• Use red food coloring to make meringue mushroom tops:
  • Once the meringue is ready, divide the preparation into two halves. Add a few drops of red food coloring to one half and mix for about 30 seconds.
  • Pipe the white meringue to make stems, and pipe mushroom caps using the red-colored meringue.
  • Take a small amount of white meringue with a toothpick and make dots on red meringue caps. Then, bake as directed.

• Experiment with a mushroom shape and size of mushroom meringues. According to Maida Heatter, "Smaller or larger mushrooms are equally attractive." Pastry chef Caitlin Dysart exaggerates meringue mushrooms, her favorite decoration of a traditional Bûche de Noël.

• Make more realistic mushrooms by rubbing cocoa powder into the baked meringues and buffing their caps and stems.
