Ingredients
2 cups whole milk
Zest of 1 Meyer lemon
1 cup Meyer-lemon juice (about 6 lemons)
5 large egg yolks
3/4 cup sugar
1 cup heavy cream
Preparation
In a medium saucepan, heat milk and lemon zest. Bring to a gentle boil, cover, and remove from heat. Steep for 30 minutes.
In a small saucepan, cook juice over medium-low heat until reduced by three-quarters, 30 to 40 minutes. Allow syrup to cool completely.
Combine egg yolks and sugar in the bowl of an electric mixer. Beat at medium-high speed until very thick and pale yellow, 3 to 5 minutes. Meanwhile, return milk to a simmer.
Add half the milk to egg-yolk mixture and whisk until blended. Stir into remaining milk and cook over low heat, stirring constantly, until mixture is thick enough to coat a spoon.
Remove from heat and immediately stir in cream. Pass mixture through a strainer into a medium bowl set over an ice bath to chill. Stir in lemon syrup, then freeze in an ice-cream maker according to manufacturer’s instructions. Store in a plastic container.
