If you've made a mint chocolate chip ice cream before, this recipe follows the same basic procedure. But while mint leaves are usually steeped in the cream for upwards of an hour or two before getting strained out, basil benefits more from a short initial steeping before getting blended into the base. I forgo chocolate chips or drizzling melted chocolate for simply shaving chocolate directly into the ice cream as it's finishing the churn.

The lemon butter cookies are an adaption of Jenny McCoy's (of A Voce fame) all-purpose cookie dough. My changes include significantly upping the lemon zest and swapping all-purpose flour for low-protein cake flour, which keeps these cookies soft and slightly chewy even at freezer temperatures (and prevents ice cream from squishing out the sides). Be advised that these cookies spread a lot; any more than ten to a half-sheet pan and they're likely to bump edges (but that's hardly the end of the world).

Ingredients

For basil chocolate chip ice cream:
3 cups half-and-half (or 1 1/2 cups each cream and milk)
3 cups washed basil leaves and stems, lightly packed (about one large bunch)
3/4 teaspoon kosher salt
3/4 cup sugar
6 egg yolks
1/2 teaspoon lemon zest
2 ounces dark chocolate, shaved fine with a vegetable peeler
For lemon butter cookies:
1/2 pound (2 sticks) unsalted butter, at room temperature
3/4 cup dark brown sugar, packed
1/2 cup sugar
Zest of three lemons
1 1/2 teaspoons kosher salt
1 egg
1/2 teaspoon vanilla extract
2 1/4 cups cake flour

Directions

For basil chocolate chip ice cream: In a medium saucepan, bring half-and-half to a simmer, then add basil and salt. Cover and barely simmer for 10 to 15 minutes, stirring occasionally. Meanwhile, in a large bowl, whisk sugar into egg yolks until they lighten in color and become thick and ribbon-like.
Transfer dairy and basil to blender, and carefully blend until smooth. (If your blender has a stopper in the center of the lid for adding ingredients, remove it and cover the hole with a few sheets of paper towel—this will keep hot dairy from splashing out at you.) Pour purée through a strainer into egg yolk mixture, whisking constantly until thoroughly combined.
Return custard to saucepan over low heat and stir constantly until it coats the back of a spoon and a finger swipe leaves a clean line. Pour custard through strainer into an airtight container. Stir in lemon zest and refrigerate overnight, or at least 6 hours. The next day, churn in ice cream machine according to manufacturer's instructions. In last minute of churn, slowly pour in shaved chocolate (best kept in the freezer until you need it). Transfer ice cream back to container to freeze for two to three hours, or serve immediately as soft serve.
For lemon butter cookies: Preheat oven to 350°F. Place oven racks in upper and lower thirds of oven. In the bowl of an electric mixer, cream butter with both sugars, lemon zest, and salt on high speed until very light with little graininess, scraping down bowl as needed. Reduce mixer to medium and add in egg and vanilla, scraping down sides of bowl until fully combined. Reduce mixer speed to low and add flour in three installments, scraping down bowl between each installment.
Using a two-tablespoon scoop, portion out 20 balls of dough on two parchment-lined cookie sheets, leaving as much room as possible for cookies to spread out. Lightly pat into flat disks, then transfer to freezer or refrigerator to firm up for 10 to 15 minutes. Bake for 10 minutes, then rotate pans 180° and swap positions on racks. Bake for another 10 minutes, or until edges are a firmer, darker brown and a spatula can easily lift a cookie without it drooping. Transfer to cooling racks and cool completely.
Assembling sandwiches: For each sandwich, scoop three to four tablespoons of ice cream onto half the cookies. Use a small offset spatula or a knife to spread ice cream flat, then cover with remaining cookies. Serve immediately or wrap tightly in plastic wrap and freeze. Sandwiches can be served straight from freezer, but ice cream benefits from a 5- to 10-minute thaw on the counter before eating.
