Makes 1 generous quart/liter custard
THERE’S SOMETHING SO WONDERFULLY NOSTALGIC ABOUT FROZEN CUSTARD, it’s so simple and yet so flavorful, a balm on a hot summer day. The seasonal openings and closings of small town custard stands give rhythm to the passage of time in a way so few things do anymore. I mean, a summer night, wearing shorts and sandals, throwing all the kids in the car, and heading out for a cone after dinner on a Tuesday, just because? Sitting at wobbly table while the sun sets, next to kids in Little League jerseys with waffle cones, chocolate-dipped and sprinkled, and tired mothers using a scoop as Xanax. Grandmothers ordering a neat little single cup; dads with their milk shakes, because that’s such a dad thing to do. That’s the good stuff, right there.
But if you ever have the urge to make your own, I’m going to leave this winner right here. With a subtle kiss of brown sugar and a swirl of sour cream, there’s just enough crave-worthy edge here to make you wonder if you should get into the frozen custard business.
6 large egg yolks
1½ cups/338 g whole milk
1 cup/240 g heavy whipping cream
⅓ cup/75 g light brown sugar
⅓ cup/67 g granulated sugar
3 tablespoons/63 g corn syrup
⅛ teaspoon fine sea salt
¼ cup/60 g full-fat sour cream
2 teaspoons pure vanilla bean paste or pure vanilla extract
In a large bowl, whisk the egg yolks until well beaten.
In a 2- to 2½-quart/1.9 to 2.4 L saucepan, combine the milk, cream, brown and granulated sugar, corn syrup, and salt. Bring to a bare simmer over medium-high heat, being careful not to let the mixture boil.
Remove the pan from the heat and slowly drizzle the hot milk mixture into the egg yolks, whisking vigorously until all the liquid has been added. Pour the egg mixture back into the saucepan and place it back on the stove over medium heat. Clip a candy thermometer to the pan. Stirring constantly, cook the custard until slightly thickened and registers a temperature of at least 160°F/71°C. Pour the custard through a sieve into a large bowl. Whisk in the sour cream and vanilla bean paste. Cover the bowl and chill thoroughly in the refrigerator, at least 4 hours or overnight.
Freeze the custard in an ice-cream machine according to the manufacturer’s instructions. Transfer the soft-set frozen custard to a 1-quart/1 L container with a tight-fitting lid and freeze until firm.
