Out of my ice cream experiments thus far, this sweet corn ice cream is one of my favorites. It's like a sweet, frozen creamed corn. This recipe is very rich, so feel free to add more milk. I didn't do a great job of removing the solid corn puree, but the ice cream tasted fine with a little bit of corn texture. The tricky part of this custard mix was determining when it was finished cooking. The corn puree makes the base very thick to begin with, so it was hard for me to use the spoon trick. I would recommend using a thermometer.
Sweet Corn Ice Cream
Adapted from Epicurious/Gramercy Tavern
Yield: Makes a scant quart
4 ears fresh corn, shucked
2 cups milk
2 cups heavy cream
3/4 cup sugar
9 large egg yolks
1. Using a large knife, slice the kernels off the corn cobs and place in a large saucepan. Break the cobs into thirds and add them to the pot along with the milk, cream, and 1/2 cup of the sugar. Bring the mixture to a boil, stirring, then turn off the heat. Using an immersion mixer or a blender, puree the corn kernels (not the cobs). Infuse for 1 hour.
2. Bring the mixture back to a simmer, then turn off the heat. In a small bowl, whisk the egg yolks and remaining 1/4 cup of sugar. Temper the eggs and return the mixture to the pan. Cook over medium-low heat, stirring constantly, until the custard thickens enough to coat the spoon, about 10 minutes.
3. Pass the custard through a fine sieve, pressing down hard on the solids, discard solids. Let the custard cool, then cover and chill for at least 4 hours. Freeze in an ice cream maker according to the manufacturer's directions.
