De-stem your mint off the stalk
Tear the mint leaves into small pieces to allow all of the mint oil to be released
Combine milk and heavy cream in a medium pan
Sprinkle in mint leaves
Place over medium-low heat, stirring regularly, until it reaches 180 degrees
Remove from heat and cover with a lid.
Let sit for at least 2 hours for maximum mint flavor
Strain mint milk mixture through a fine-mesh sieve into a large bowl.
Press all of the liquid out of the mint leaves with a wooden spoon (cream will look light green/yellow)
Transfer mint milk into your medium sauce pan and heat until it just starts to boil, giving it a regular stir so it doesn’t burn
In a medium bowl, whisk together egg yolks and sugar until smooth and a light yellow color.
Slowly pour 1/2 cup of your heated milk mixture into the egg yolk to temper, whisking to combine
Pour the tempered egg mixture into the mint milk, stirring with a wooden spoon to combine and create a custard.
Simmer mixture, while stirring constantly, until the back of the spoon is coated (about 170 degrees)
Pour custard through a fine-mesh sieve into a large, heat-proof bowl.
Stir in vanilla and salt.
Allow custard to cool down to room temperature (you can place the custard bowl in an ice bath- take a larger bowl with ice and put your smaller bowl of cream mixture on top- to speed up the process)
Cover or transfer to an airtight container.
Set in refrigerator for at least 4 hours or overnight until completely chilled.
Pour the mixture into your ice cream maker
Churn ice cream mixture for 25 minutes
During the last minute of churning, add in 2-3 tbsps of very finely chopped fresh mint (*see notes below for chocolate variations)
Scoop ice cream into a freezer-safe container, drizzling a little more chocolate ontop.
Harden in freezer for at least 4 hours or overnight
