Equipment
Method
- Heat the oven to 200°F.
- Line two 13x18-inch sheet pans with parchment paper.
- In a heatproof mixing bowl, whisk the egg whites, sugar, and cream of tartar.
- Set the bowl over a saucepan of gently simmering water, making sure the bowl does not touch the water, and whisk constantly until the mixture reaches 160°F and the sugar is dissolved, 3 to 5 minutes.
- Remove the bowl from the saucepan and beat with an electric mixer on high speed until the meringue is cool to the touch and holds stiff, glossy peaks, 8 to 12 minutes.
- Beat in the vanilla and green food coloring until evenly colored.
- Transfer the meringue to a piping bag fitted with a large open-star tip and pipe 2-inch-tall trees about 1 inch apart on the prepared pans.
- Sprinkle the trees with the jimmies.
- Bake for 1 1/2 to 2 hours, switching the pans between racks and rotating them front to back halfway through, until the meringues feel dry and lift cleanly from the parchment.
- Turn off the oven and leave the meringues inside with the door closed for 1 hour.
- Remove the meringues and cool completely.
Notes
For the best crisp texture, keep moisture away from the meringues and store them in an airtight container; they keep for up to 3 days in the refrigerator, though refrigeration may soften them. Freezer: no, as thawing can make them sticky. They are naturally gluten-free, so no dietary swap is needed.
