The first go round, I infused with fresh ginger and mint from option 1, and then added lemon juice from option 2. My inspiration was a lemon sorbet recipe I had tried before. I didn't really care for the outcome, though. The mint was too much. So the next time I replaced the mint with lemon zest. That did the trick! The cookies are recipes from Fine Cooking Cookie magazine a couple of years ago. One was the Double Ginger Crackles on page 29 and the other is the Ginger & Lemon Cookies on page 43. Both cookie recipes use crystalized ginger. I also crushed up some of the Lemon cookies and added to the rest of the ice cream.
Ginger Lemon Ice Cream
Yields about 1 quart
2 cups heavy cream
1 cup whole milk
3/4 cup granulated sugar
1/2 cup peeled, thinly sliced fresh ginger
Zest of 4 medium Lemons
5 large egg yolks
1/4 cup fresh lemon juice
In a medium saucepan, mix 1 cup of the cream with the milk, sugar, and a pinch of salt. Warm the cream mixture over medium-high heat, stirring occasionally, until the sugar dissolves and tiny bubbles begin to form around the edge of the pan, 3 to 4 minutes.
Stir in the ginger and lemon zest. Cover, remove from the heat, and let sit for 1 hour. Taste and let sit longer if you want a stronger flavor.
Prepare an ice bath by filling a large bowl with several inches of ice water. Set a smaller metal bowl (one that holds at least 1-1/2 quarts) in the ice water. Pour the remaining cup of cream into the inner bowl (this helps the custard cool quicker when you pour it in later). Set a fine strainer on top. Whisk the egg yolks in a medium bowl.
Rewarm the cream mixture over medium-high heat until tiny bubbles begin to form around the edge of the pan, 1 to 2 minutes. In a steady stream, pour half of the warm cream mixture into the egg yolks, whisking constantly to prevent the eggs from curdling.
Pour the egg mixture back into the saucepan and cook over low heat, stirring constantly and scraping the bottom with a heatproof rubber spatula until the custard thickens slightly (it should be thick enough to coat the spatula and hold a line drawn through it with a finger), 4 to 8 minutes. An instant-read thermometer should read 175° to 180°F at this point. Don’t let the sauce overheat or boil, or it will curdle. Immediately strain the custard into the cold cream in the ice bath. Press firmly on the ginger and lemon zest in the strainer with the spatula to extract as much flavor as possible.
Cool the custard to below 70°F by stirring it over the ice bath. Stir the lemon juice into the cooled custard.
Refrigerate the custard until completely chilled, at least 4 hours. Then freeze the custard in your ice cream maker according to the manufacturer’s instructions. Transfer the ice cream to an air-tight container, and freeze for at least 4 hours or up to 2 weeks.
