From AM New York and Otto:
Serves 6 (makes approximately 5 cups)
To obtain a fresh, minty flavor, use black mint or peppermint, available at local greenmarkets. Stokes Farm, at Union Square greenmarket, is a good source.
Ingredients:
1 quart milk
2 bunches (about 1 cup picked leaves) fresh mint, washed
1/2 vanilla bean, split and scraped
1/2 cup heavy cream
11/2 cups sugar
10 egg yolks
1/4 tsp. salt
1 cup chopped bittersweet chocolate (optional)
Directions:
1. Bring the milk to a simmer in a heavy bottomed saucepan.
2. Remove the pan from the heat, and add the mint and vanilla bean scrapings to the milk. Steep uncovered for 30 minutes.
3. Strain the milk, and discard the mint leaves. Return the milk to the saucepan, along with the heavy cream and 1/2 of the sugar. Bring the mint milk to a simmer, stirring to dissolve the sugar.
4. Whisk the egg yolks, the salt and the remaining sugar in a metal bowl. Slowly pour some of the hot milk into the yolk mixture, whisking to incorporate. Be careful not to add too much hot milk at once, as this will curdle the eggs.
5. Add the tempered yolks to the saucepan. Cook over low heat, stirring constantly, until the mixture thickens slightly and a little steam starts to rise from the mixture.
6. Remove the pan from the heat, and strain the custard into a bowl. Chill immediately by placing the bowl in a slightly larger bowl filled with ice, stirring quickly to promote fast, even cooling.
7. Chill the custard in the refrigerator for at least 3 hours, then process in the ice-cream maker of your choice.
8. If you want to add chocolate chips to the gelato, chill the chopped chocolate in the refrigerator, then quickly fold them into the turned gelato after removing from your ice-cream maker. Chill the gelato in the freezer afterward to firm it up.
