Vegan Meringue Cookies

Position a rack in upper third of oven; preheat to 200 degrees F. Line a large baking sheet with parchment paper.

Beat chickpea liquid in a mixing bowl with an electric mixer on high speed until stiff peaks form, 5 to 10 minutes. Add sugar, about 1 tablespoon at a time, and continue beating until very glossy, about 5 minutes. Add vanilla (or almond) extract and beat for 1 minute more.

Place a dot of the meringue under each corner of the parchment paper to secure it to the pan. Spoon the meringue into a 1-gallon sealable plastic bag (or pastry bag fitted with a 1/2-inch plain tip). Seal the bag almost completely, leaving a small opening for air to escape from the top as you squeeze. Snip off a bottom corner to make a 3/4-inch-wide opening. Fold the top of the bag over a few times, then gently push the meringue down to the snipped corner. Holding the bag perpendicular to the pan, pipe the meringue into 1 1/2-inch cookies, spacing them about 1/2 inch apart.

Bake the meringues on the upper rack until they are dry and crispy, 1 1/2 to 2 hours. Turn off the oven and leave the meringues in the oven, with the door closed, for 1 hour more.
