Lemon Gelato

Step 1

In a small saucepan combine milk and lemon zest. Place over medium-low heat just until steaming; do not boil. Remove from heat, cover, and allow mixture to infuse for about 20 minutes.

Step 2

In a medium bowl, whisk together egg yolks and sugar. Strain infused milk into a pitcher, then whisk it into yolk mixture.

Step 3

Pour mixture into a clean saucepan, and place over medium-low heat. Stir constantly with a wooden spoon until it forms a custard thick enough to coat back of spoon, about 10 minutes. (Do not overheat or it will curdle.)

Step 4

Cool mixture by placing bottom of pan in several inches of cold water; give it a stir. Transfer to a bowl and refrigerate until well chilled, about 1 hour. Freeze in an ice cream maker according to manufacturer's instructions.
