I know this sounds weird, but you aren't going to believe how good it is. I've been thinking about making different ice creams since I got my freezer last month, so when the challenge was cucumbers, I thought ice cream. I added a hint of mint and some finely chopped white chocolate to make it interesting. I like how the white chocolate disappears into the ice cream and then surprises you -- but you can make it easier by using mini chocolate morsels. Chopped salted peanuts would be good, too.

Test Kitchen Notes
This fun, quirky recipe really works! I knew I was going to love the cucumber-mint flavor combination, but I had no idea how much I'd like them blended into the creamy richness of a vanilla ice cream. What makes this so fun is that it’s really not obvious that the unusual flavor component is cucumber. I left the white chocolate out, and am glad I did, as the ice cream was not only somewhat light, but also not too sweet. I heartily encourage you to try it. Two enthusiastic and very pleasantly surprised thumbs up!! —AntoniaJames
about 1 1/2 quarts
large English cucumber, peeled, seeded, and roughly chopped
packed mint leaves
whole milk or half and half
large egg yolks
generous pinch kosher salt
1/2 to 1 cups
very finely chopped white chocolate (or mini chocolate chips), optional
In This Recipe
Purée the cucumber in a blender or food processor. You should have a scant 2/3 cup of puree, some of which will be liquid. You're going to strain out the solids, so this is fine. (Alternatively, if you have a juicer, you could simply juice the cucumber.)
Put the mint leaves and the sugar into the food processor bowl. Process until the mint is finely ground. (You could also grind them together with a mortar and pestle. )
In a medium saucepan, warm the milk and heavy cream over medium heat. Stir occasionally.
Whisk the egg yolks until smooth, then add the sugar and mint mixture and whisk until thoroughly combined. When the milk mixture steams and is hot but not simmering, whisk 1/2 cup of the hot milk into the egg mixture to temper the egg yolks.
Take the saucepan off the heat and stir in the tempered egg mixture.
Return the saucepan to the stove over medium heat. Add the honey and salt. Cook, stirring, until the mixture is between 175 and 180 degrees, or thick enough to coat the back of the spoon. This will take about 5 minutes. Do not allow the mixture to boil. (When you draw your finger across the spoon, it should leave a clear mark through the custard. )
Strain the cucumber through a fine mesh strainer into the custard. Stir in the vanilla extract.
Cool the custard somewhat in an ice water bath and then strain it (to strain out some of the mint leaves) into a pitcher. Refrigerate until cold.
Pour the custard into your ice cream freezer and churn according to the manufacturer's directions. When the ice cream is starting to thicken (and beginning look like ice cream), about 5 minutes before it's ready, pour in the white chocolate.
