Instructions
Before You Start
Preheat oven to 212℉ / 100℃.
Wipe the bowl and whisk attachment with vinegar (don't worry, nothing will smell or taste like vinegar in the end).
Weigh the egg whites and use double the weight of the egg whites in sugar. For example, my egg whites weighed 76 grams, so I used 152 grams of superfine sugar, which is about ¾ cups.
2 egg whites (about 76g), ¾ cup superfine sugar (152g)
How to make your own superfine sugar: Pulse 2 tablespoons of the sugar in a food processor until it's finer, but NOT powdered sugar and then pour it into a bowl. Repeat the process with the remaining sugar. (By pulsing the sugar 2 tablespoons at a time, you can monitor how fine the sugar gets without becoming powdered). Set it aside.
Make The Meringues
Put the egg whites in the bowl of a stand mixer. You could use a hand mixer, but it will take longer.
Start with the whisk on low speed and after a few seconds when you see bubbles, increase the speed to medium and add the salt and the vinegar.
pinch of salt, ¼ teaspoon white vinegar
Gradually increase the speed to high until it looks soapy and there are soft peaks.
Start adding the sugar, a tablespoon at a time while still beating.
Add the vanilla and beat until it gets thick and glossy and there are stiff peaks, about 8 minutes more. It will be thick and marshmallowy.
½ teaspoon vanilla
If you want to color meringues, I suggest using gel food coloring. Add a very tiny amount with a toothpick. Use the whisk attachment to mix it in evenly.
Pipe Christmas Trees & Bake
Fill a piping bag fitted with a large French star tip and pipe a blob under the parchment paper in each corner of the baking sheet. Then press the parchment paper on top, so it sticks. This will prevent the paper from moving around.
Hold the piping bag completely vertical and straight and pipe a big blog. Without pulling away completely, gently pull up and pipe a smaller blob, then pull up a little bit again and pipe a really small blob. Then pull the piping bag away.
Don't make the trees too high, because they'll droop.
Add edible glitter or sprinkles, if using.
edible glitter or sprinkles (optional)
Bake for one hour for meringues that are soft and mallowy inside, or 90 minutes for really crunchy meringues. The longer you bake them, the crunchier they get.
After the time is up, turn off the oven and let the meringues cool inside for at least one hour. DO NOT OPEN THE OVEN DOOR DURING THIS TIME.
The meringues are done when they are dried throughout and you can easily pull off a tree from the parchment paper. It should be hard outside, not sticky.
Enjoy!
Notes
Store these Christmas meringue cookies in an airtight container at room temperature for up to 2 weeks.Tips for Perfect Meringues
Avoid baking meringues on humid days, as they can absorb moisture and become sticky.
Clean Equipment Thoroughly. Make sure bowls and utensils are grease-free; even a trace can prevent proper whipping. Cleaning with vinegar works well and won’t affect the flavor.
Separate Eggs Carefully. Crack each egg into a small bowl first to avoid contaminating the batch if a yolk breaks.
Use Superfine Sugar. Superfine sugar dissolves better for smooth meringues. If unavailable, pulse regular sugar in a food processor until finer, but not powdered.
Add Sugar Gradually. Slowly drizzle sugar into the running mixer, a teaspoon or tablespoon at a time, for glossy, stable peaks.
Color Carefully. For colored meringues, use gel food coloring. Add a very tiny amount with a toothpick and mix evenly.
Keep the piping bag straight for proper tree shapes; avoid making the trees too big to prevent them from drooping.
Pipe Immediately. Pipe your meringue as soon as it's ready to preserve its structure and consistency.
Let meringues rest after baking, leave them in the oven for at least an hour without opening the door to allow them to set.
Hand Mixer Option. If using a hand mixer, expect a much longer mixing time compared to a stand mixer.
