Matcha White Chocolate Ice Cream & Kumquat Pound Cake
It also goes without saying that despite my initial excitement, anticipation and better intentions, work, life and, let's face it, plain old laziness got in the way and the slender volume has been languishing un-used until the weekend just past. The catalyst? Some kumquats I'd picked up on impulse on my grocery run earlier in the week (for more ideas on what to do with kumquats, see this breathtaking post).
While I personally use a Gaggia Gelatiera, this particular batch was churned in a Cuisinart Ice Cream Professional, a machine I've been given the opportunity to test-run for the purposes of designing an ice cream class to be held at the school, tentatively scheduled for sometime in the second quarter of next year. It is certainly possible to make ice cream without an ice cream machine, but I for one don't have the patience or inclination for that kind of self-punishment, not to mention the ice cream never quite acquires the absolutely smooth texture made possible by a good machine. But the reality is that most don't make ice cream frequently enough to justify the kind of serious money your average high end model with a built-in compressor system costs. Self-refrigerating units are the way to go if you don't want to hassle with canisters that require pre-freezing (plus much advance planning and ample freezer space). Such efficacy and efficiency (these heavy duty machines can churn many batches consecutively without skipping a beat) usually command a premium that can be downright shocking to the uninitiated. Which is where Cuisinart's sleek and smart machine (check it out at Shermay's Cooking School; it's the latest addition to their choice inventory of nifty cook's tools and kitchen must-haves) comes into the picture - equipped with a self-freezing compressor, fully automatic, and capable of delivering the kind of results hitherto associated with fancier (and far pricier) models. In other words, it's terrific value.
Makes about 1 litre
375 gm heavy cream
375 gm milk
100 gm caster sugar
1/8 tsp fine salt
4 large egg yolks
200 gm white chocolate, finely chopped
2 Tbsp matcha
1 Tbsp mirin
Place a chinoise over a medium bowl and set aside. In a medium heavy saucepan, bring the cream, milk, sugar and salt to a simmer over low heat, stirring constantly.
Meanwhile, in a medium bowl, whisk the egg yolks just sufficiently to break them up. Whisking constantly, pour the hot cream mixture over the egg yolks in a slow and steady stream.
Scrape mixture back into saucepan and cook the custard over low heat, stirring constantly, until the mixture thickens sufficiently to coat the back of a wooden spoon (if using a thermometer, the custard should register no more than 180°F). Immediately strain the mixture through the chinoise into the waiting bowl. Set aside.
Meanwhile, bring a saucepan of water to the boil. Place the white chocolate in a heatproof bowl that will sit snugly atop the pan of water. Once water comes to the boil, turn off the heat and place the bowl of chocolate atop the pan, stirring with a dry silicone spatula until melted and completely smooth. Remove from pan of water. Scrape the warm custard into the bowl of melted white chocolate and stir to blend. Set aside.
In a small bowl, mix together the matcha and mirin to form a smooth paste. Scrape this paste into the bowl of white chocolate custard, whisking vigorously to blend thoroughly. Let cool then refrigerate, covered, until chilled (preferably overnight).
Freeze according to the instructions for your ice cream machine.
