Heat milk, basil and ¼ cup sugar, with a pinch of salt, in a heavy saucepan. Bring to a boil stirring constantly. Once the mixture comes to a boil, remove from the heat and let steep for 30 minutes. After 30 minutes, pour the mixture through a strainer to remove the basil leaves.
- 2 cups whole milk
- 1 cup basil leaves
- ½ cup sugar
- Pinch of Salt
- 4 large egg yolks
- ½ cup well-chilled heavy cream
With a hand-held mixer, beat the yolks and remaining ¼ cup sugar in a bowl until thick and pale (about 1 minute). Add the milk mixture in a slow stream and beat until combined. Pour mixture into a clean saucepan and cook over moderate heat. Be sure to stir constantly. The mixture will begin to thicken and is ready when it coats the back of a wooden spoon – this will take around 6 minutes of stirring. Do not let the mixture come to a boil.
Remove from the heat and poor in to a small bowl. Place the bowl in a larger bowl of ice water and stir until cold, around 12 minutes. (I recommend making the ice bath before you cook the custard over the stove – the custard will cook quickly and, if you don’t cool it down immediately, you risk curdling the mixture).
Stir in the cream and freeze in the ice cream maker. Once frozen, place the ice cream in an airtight container and put in the freezer to harden for at least 2 hours before serving. Enjoy!
