Stunning mint meringue cookie with a wintry mint flavor and a hint of green color. Quick and easy-to-make cookies melt in your mouth.
Preheat oven to 200℉/90℃ or 175℉/80℃ if using convection mode. Line 2 sheet pans with parchment paper and set aside.
Double-check that your mixer bowl is extra clean and dry as that will cause the egg whites to not whip up properly. In a bowl of an electric mixer fitted with the whisk attachment, whisk egg whites and pinch of salt on low-medium speed until foamy, approximately 30-40 seconds.
Pour in the distilled white vinegar and cornstarch. Continue whisking on medium speed for one minute.
While mixer is running, add the sugar, one tablespoon at a time, and continue whisking on medium-high speed until stiff peaks form, meringue is glossy and completely smooth but not dry, and the sugar is fully dissolved (this part of adding the sugar and continue beating may take 4-6 minutes).
Beat in Creme de Menthe and optional food coloring until fully combined, scraping down the sides of the bowl and folding gently by hand to finish.
Immediately spoon meringue into a piping bag and pipe the meringue onto the prepared baking sheet. For piping the tree shape, view the notes below. These cookies don’t spread, so you can place them quite close to each other.
Place on a low-to-middle rack of the oven and bake for 80-90 minutes, or until the meringues are dry, their center isn’t sticky, and they are easily lifted from the parchment paper with their bases intact. Turn off the oven and, without removing, let meringues cool completely for at least four hours or overnight (ideal).
If you have a scale, weigh the egg whites for best results. Make sure there are no egg yolks in there or it will ruin the meringue.
Using a low oven temp and parchment paper will prevent the meringue bases from browning.
Remember that there’s no harm in baking the meringues for a longer time, so if you don’t feel that they’re quite ready yet, continue letting them bake.
To create your Mint Meringues in the shape of evergreen trees, you’ll need an open star-shaped piping tip. Here’s a quick guide to achieve this festive shape:
Meringue cookies will keep for 2 weeks in an airtight container at room temperature. Serve in a bowl or get creative and crush these cookies over chocolate pudding, chocolate ice cream, or chocolate mousse!
Crushing meringue cookies also creates an "edible snow" for surrounding your gingerbread house too.
