This spiked chocolate milk shake has been on the menu at Copita, chef and cookbook author Joanne Weir's restaurant in Sausalito, California, since day one. "It blends together spiced Oaxacan chocolate and the richest of chocolate ice creams with guajillo chile, cinnamon, vanilla extract, and a generous splash of tequila añejo," writes Weir. "It's the richest, most decadent milk shake you'll ever taste, and it leaves you feeling all warm and fuzzy."
1 1/2 cups whole milk
1 1/2 cups heavy whipping cream
2/3 cup sugar
4 cinnamon sticks (3 in. long)
6 ounces bittersweet chocolate, finely chopped
2 teaspoons minced chipotle chile in adobo sauce
7 large egg yolks
Pinch of guajillo chile powder
1/2 teaspoon vanilla extract
1/4 cup tequila añejo
10 ice cubes
How to Make It
In a saucepan, combine milk, cream, sugar, and cinnamon. Heat over medium heat, stirring, until small bubbles appear along edges of pan and sugar has dissolved. Cover; set aside off the heat to steep 2 hours.
Put chocolate and chipotle in a heatproof bowl and set aside. In a bowl, whisk egg yolks until blended. Return steeped milk mixture to medium heat to warm. Drizzle milk mixture into yolks, whisking constantly, then pour milk-egg yolk mixture back into saucepan. Cook over medium heat, stirring constantly, until mixture thickens, 2 to 4 minutes. Do not boil.
Remove from heat and strain through a fine-mesh strainer set over bowl of chocolate. Add chile powder and vanilla, then whisk until chocolate has melted and mixture is smooth. Cover and chill until cold.
Pour chilled custard into an ice cream maker and freeze according to manufacturer's instructions. Transfer ice cream to an airtight container and store in the freezer until ready to make milk shakes. You will have about 1 generous quart; plan to use it within 1 week.
To make milk shakes, in 2 equal batches, combine ice cream, tequila, and ice cubes in a blender. Process until ice cubes are completely incorporated, 1 to 1 1/2 minutes. Stir batches together, mixing well. Pour into glasses to serve.
