Chocolate Mint Chip Ice Cream
I was a bad kid in high school. I had a nose ring. I had pink and blue hair (at the same time). I wore ripped clothes to school...when I went to school, that is.
And I hung out with other bad kids (who also sported piercings, dyed hair and tattered clothes). We would skip first (and sometimes...all of them) period and go breakfast at cheap diners or doughnut shops. Or drive to the beach for a picnic. Or sneak into art museums. Or (a personal favorite) go do our homework on a friend's uncle's vacated boat in the L.A. marina, where we were free to enjoy the contents of the liquor cabinet. (Hey, at least we did our homework.)
In the strip-mall Hell that is the San Fernando Valley, there wasn't much for bad kids to do at night, so we would often roam the aisles of Thrifty's drug store, trying on make-up, looking at tchotchkes and snacking on their 99¢ ice cream cones. The cones tasted like sugary cardboard, the pecan praline like movie theater 'butter,' and the mint chip glowed verdantly.
Many years later, long after I'd removed my nose - and then, eyebrow - piercings and my hair had returned to it's previously scheduled auburn (I still wear ripped clothes, but mostly in the privacy of my own home), I made ice cream with fresh mint. I steeped the mint in the warm dairy, then cooked and chilled the custard and churned it up. Though it tasted fresh and herbaceous, I admit I was disappointed when the finished product remained ecru in color. The recipe suggested adding a drop or two of green food coloring if I was declassé enough to have a problem with that fact. But being older, wiser and anti-food (and hair) coloring, I thought I could accept a life of ivory-colored mint ice cream.
But then I got a job in the pastry kitchen at Farallon, and I learned that I could have my green ice cream, and eat it without feeling (too) bad.
The secret lay in the same technique that I've learned to use in order to prevent the basil in pesto from oxidizing. The mint was blanched briefly in boiling water, then shocked in ice water, before being pureed with the chilled ice cream base and strained. The result was an ice cream as minty in color as it was in flavor.
At Farallon, we sandwiched tiny scoops of this iced green confection with quarter-sized fudgy chocolate cookies, and arranged them with a dozen other miniscule confections on tiered silver stands for an assortment of 'petite sweets.' Don't tell, but I would often munch a couple during my plating shift; chocolate mint heaven.
When I learned that there is a veritable variety of mint called 'chocolate mint,' I longed to get my hands on some to make chocolate mint chip ice cream. With burgundy-tipped emerald leaves, chocolate mint conveys all the cool freshness of the more familiar varieties, with a touch of warmth from earthy cacao undertones. The other day, when my green-thumbed friend let on that she had a barrel of chocolate mint thriving in her garden, I confessed to her my dream. And lo, a bunch of chocolate mint manifested itself at my door the very next day. I dug out Farallon's recipe, which I'd jotted down before I left, and adapted the method to use my favorite ice cream base.
Remembering his handsome post on mint chip from last year, I consulted David L, my ice cream guru, for chocolate quantity and chip technique. I once made the stracciatella from his ice cream book, in which melted chocolate is slowly drizzled into the churning ice cream (I made the toasted hazelnut-milk chocolate from his book, and oh was it good). But for his recent mint chip recipe, David 'scribbles' the melted chocolate between layers of churned ice cream spread into a loaf pan. Since the stracciatella technique left quite a bit of chocolate on my dasher, I enjoyed the scribble technique.
Plus, it enabled me to get in touch with my inner Jackson Pollock. And my inner bad kid, all at once.
If you're feeling extra bad, pair this ice cream with a gooey whiskey brownie, triple chocolate cookie, or chocolate bouchon cake.
I won't tell.

Chocolate Mint Chip Ice Cream
Makes about 5 cups, about 8 servings
With burgundy-tipped emerald leaves, chocolate mint conveys all the cool freshness of peppermint with a bit of warmth from earthy cacao undertones. Like all mints, it grows like a weed (or so I'm told), but if, like me, you have less than 2-square-feet of outdoor space, and (unlike me, luckily) lack generous and green-thumbed friends, you may be able to find chocolate mint at a farmer's market. Otherwise, substitute spear or peppermint; both will be delicious. Another soft herb, such as basil in any of its varieties (cinnamon, lemon, thai, or the standard Italian stuff) or lemon verbena, would likely work well, too (though I would omit the chocolate).
1 cup half and half, plus another 1/2 cup
4 large egg yolks
1/2 cup sugar
1 cup heavy cream
1 bunch chocolate (or other) mint, leaves only (1 cup medium-packed), washed and dried
4 ounces (about 1 cup) chopped bittersweet chocolate (I used 70% cacao mass)
Make the custard base:
Heat 1 cup of half and half in a medium saucepan over a medium flame until warm and steamy, and small bubbles form around the sides of the pot, swirling occasionally.
Pour the heavy cream and remaining 1/2 cup of half and half into a large bowl and place a fine-mesh strainer over the top. Set aside.
In a medium bowl placed on a damp towel for stability, whisk together the yolks, sugar and salt.
Slowly drizzle the warm half and half into the yolk mixture, whisking constantly, then scrape the mixture back into the pot. Cook over low heat, stirring constantly with a heat-proof rubber spatula, until the mixture just begins to 'stick' (form a film on) the bottom of the pot, and/or reaches 170º on an instant-read thermometer.
Immediately pour the custard through the strainer and into the cold dairy. Stir to combine, then chill the mixture in the fridge for at least 4 hours or (preferably) overnight, and up to 4 days.
When you're ready to churn the ice cream, blanch and shock the mint:
Bring a quart of water to a boil in a large saucepan. Have a medium bowl filled with ice water handy, as well as a slotted spoon. Dump the mint leaves into the boiling water, swish to submerge, and count to 10. Turn off the heat, fish out the leaves with the slotted spoon and plunge them into the ice water. (You can use this hot water to melt the chocolate over, as per below, and later, to drink - it is essentially mint tea.)
Pull the blanched mint leaves out of the ice water and squeeze dry. Place the squeezed-dry leaves in a blender. Add about a cup of the chilled ice cream base, and puree on low speed, gradually increasing to the highest speed, eventually pouring in the rest of the ice cream base. The mixture should be fairly smooth, frothy, and mint green in color.
Strain the minty ice cream base through a fine-mesh strainer, and into a large bowl or measuring pitcher, pressing on the mint dregs to extract as much good stuff as possible. Place the mixture in the freezer for 20 - 30 minutes, stirring once or twice, to get the mixture really cold (the blending process generates a bit of heat).
Process the well-chilled ice cream base in an ice cream maker according to the manufacturer's instructions.
Meanwhile, melt the chocolate:
While the ice cream is churning, place the chocolate in a dry, medium-sized metal bowl and set over the pot of hot water from blanching the mint (above). The water should be steaming but not simmering or boiling. Stir the chocolate occasionally until completely melted. (Even a drop of water can cause chocolate to seize or clump up, so make sure the bowl and utensils are bone dry.) Hold the chocolate at a melted but cool temperature.
Place a glass or metal loaf pan or the like in the freezer. (This will help keep the ice cream cold as you layer it with the melted chocolate.)
When the ice cream is done churning, layer it with the melted chocolate:
Working quickly, scribble the bottom and sides of the chilled loaf pan with some melted chocolate, then spread a layer of ice cream over the top. (See photos in post, above.) Scribble more chocolate over the ice cream, and spread with another layer of ice cream. Continue making layers until you've used up all the chocolate and all the ice cream. Cover the pan and freeze the ice cream for at least 2 hours for a scoopable consistency, and up to several months (though good luck with that one).
