Use the liquid from a 14.5-16 oz can of beans for each recipe. The liquid also known as AQUAFABA from chickpeas or great northern or cannelini works best because they don't change the color of the food.
1/2 cup AQUAFABA
1/2 teaspoon cream of tartar (optional)
1/2 teaspoon vanilla
1/2 cup PLUS 2 tablespoons confectioners sugar
Combine all ingredients EXCEPT the sugar. Whisk/beat 10-15 minutes or
until stiff peaks appear. After peaks appear, gradually whisk/beat in
sugar. Once all sugar is added, beat for an additional 5-15 minutes
until peaks reappear.
Set the oven at 225 degrees. Spoon meringues or squeeze using a ziploc
bag onto a parchment paper on a cookie sheet. (Once you seal the
ziploc bag with the sugary mixture, cut a small diagonal in the lower
corner of the bag and squeeze the meringue onto the parchment paper.
Bake for 1-1/2 hours.
