Lemon Olive-Oil Ice Cream

Preparation

1. Step 1

   Whisk egg yolks together in a medium nonreactive bowl; set aside. Combine cream, milk, sugar, 3 teaspoons lemon zest and the salt in a medium nonreactive saucepan. Cook over medium heat, stirring occasionally, until sugar is dissolved and mixture begins to bubble around the edges. Ladle about 1 cup of the cream mixture into the egg yolks and whisk vigorously to temper the eggs.

2. Step 2

   Pour the egg and cream mixture back into the pan and whisk well to combine. Cook the mixture on medium-low heat, stirring constantly, until it thickens enough to coat the back of a spoon, about 7 minutes. Take care to not let the mixture boil. Strain the mixture through a fine mesh sieve into a large bowl.

3. Step 3

   Slowly stream in the lemon juice and olive oil while whisking constantly, then whisk in the remaining 1 teaspoon lemon zest. Chill the mixture in a bowl set over an ice bath until completely cool. Alternatively, cool the mixture completely in the refrigerator, covered, at least 4 hours, or overnight.

4. Step 4

   Just before churning, whisk the mixture thoroughly. Churn in an ice cream machine according to manufacturer’s instructions. Transfer the ice cream to a freezer-safe container, press a piece of plastic wrap against the surface, cover, and freeze until firm. Serve scoops of ice cream with a drizzle of fruity olive oil and a sprinkle of salt and lemon zest, if desired.
