Ingredients
3 tablespoons plus 1 1/2 teaspoons egg white
Pinch salt
10 mint leaves
2 tablespoons plus 1/2 teaspoons powdered sugar
Preparation
Preheat the oven to 275. Whisk the egg whites with the salt and pass through a fine sieve. Dip the mint leaves into the mixture, shake off the excess and lay on a sheet of waxed paper.
Dust leaves with the sugar and put into the oven for about 20 minutes, checking regularly, until the egg white starts to bubble up and color very slightly. To check whether the leaves are ready, take one out and cool slightly. If it is crunchy, it is ready. If not, discard it and give the others 5 minutes more.
