skyrversary

I called Natasha last month to wish her a happy one-year skyrversary. On our trip to Reykjavik, we ate the thick creamy yogurt-like deliciousness at least once a day, often twice, once even thrice. Yes, it was lovely for breakfast but it really shines in dessert. Each of the restaurants we went to had a sweet skyr course, typically layered with something frozen and something crunchy. One night, blueberry sorbet and oats. Another, strawberries and green strawberry granita. And also, sorrel granita, hazelnut gelato, merengue, and blondies. I mean, seriously people, the desserts were insane.

Just a few days after returning home, I took a first step at reproducing our desserts: I pulled out Cheryl Sternman Rule‘s Yogurt Culture to start from scratch. I inoculated a heavy pot of warmed milk with a dollop of skyr starter (Icelandic Provisions because they use “heritage cultures” and I was aiming for authenticity) and let the whole mix incubate overnight in an oven warmed only by its light. (Am I sounding overly scientific with all this inoculation and Incubation? Yeah, a little. And I’m OK with that.)

In the morning, I pulled the heavy pot from its oven incubator and was pleased to see that the curds had sunk to the bottom and the liquid whey had risen to the top. My plan was to strain the curds as if I were making Greek yogurt (not that I’ve made that), and then strain them a little bit longer.

I lifted the pot and tipped it over a bowl to pour off the whey, but the curds slid out and I lost hold of the pot and the floor was soon a slick puddle of yogurt. Warm yogurt. Turns out, the scent of warm fermenting yogurt is not only unappealing but it permeates everything. After I mopped up the floor, I had to change outfits. And after a day outside, I thought I was coming home to a dairy farm.

I’d like to say I got back on the horse, but I didn’t. I just moved on. One by one, I pulled together the components for an approximation of the simplest of our skyr desserts. There were blueberries to roast. Sorbet to churn. Cookie crumbles to bake. I then layered and layered and layered to compose a ridiculously complicated dessert.

Fancypants blueberry and skyr dessert

– Skyr

– Roasted blueberry compote

– Blueberry lime sorbet

– Oatmeal cookie crumble

Layer. Fill a glass two-thirds with skyr. Cover with blueberry compote. Top with a scoop of sorbet. Sprinkle with cookie crumble. Drizzle with a few more roasted blueberries.

Roasted blueberry compote

Just barely adapted from Cheryl Sterman Rule‘s Yogurt Culture. This is actually the first time I’ve roasted fruit – strawberries, you’re up next! – and I like how the flavors concentrate differently than stove-top compote, making a more soup-like (as opposed to stew-like) compote. The berries wrinkle up as the oven dries them out and because they’re not crowded together in a pot, they don’t reabsorb their released juice. 

If your blueberries are tart (for example, the tiny ones from Maine), add up to a tablespoon more of sugar.

Makes 1 1/2 cups

– 2 1/2 C fresh blueberries

– 2 T white sugar

– 1 T lime juice

Roast. Heat oven to 350°F. Toss 2 cups of blueberries with the sugar and spread on a parchment-lined baking sheet. Roast for 15-20 minutes until the skins burst, the berries shrivel up a bit, and the released juices thicken and slightly caramelize.

Mix. Using a bench scraper, pull the berries and juices into the center. Carefully lift the long edges of the parchment towards the center and tip the berries and their juices into a bowl. Don’t wait too long or the juices will harden. Stir in the lime juice and let cool.

Serve. Mix with yogurt (or skyr), drizzle over ice cream, or put a jar on a cheese plate.

Blueberry lime sorbet

This recipe follows the guidelines for Any-Fruit Sorbet from The Kitchn. While making simple syrup is a bit fussy and not necessary for a berry sorbet, I added this step so I could infuse mint into the sugar water concentrate. Just a tiny bit of vodka helps lower the freezing point so that the sorbet doesn’t get too hard. Depending on what type of ice cream maker you have, you might need to put the canister in the freezer the night before. 

– 1/4 C sugar, plus extra if needed

– 1/2 C water

– 4 sprigs fresh mint

– 2 lbs (about 5 C) blueberries

– 1 t lime zest

– 1 T vodka

– 2 T fresh lime juice, plus extra if needed

Simmer. Make simple syrup by combining sugar, water, and mint in a pot over medium-high heat. Simmer, stirring periodically, until the sugar dissolves. This is a very concentrated 2:1 sugar syrup as I didn’t want to add too much water. Remove from heat and cool to room temperature.

Puree. Use a blender, immersion blender, or food processor to puree the simple syrup, berries, lime zest, and vodka until smooth.

Strain. Strain mixture through a fine mesh strainer to get rid of any pesky blueberry skins and larger pieces of lemon zest.

Taste. Add the lime juice and taste the mixture for sweetness. It should be a bit sweeter than you want because the sweetness dissipates during the freezing process .(How? I have no idea.) Way too sweet? Add lime juice, teaspoon by teaspoon. Too sour? Add sugar, tablespoon by tablespoon.

Chill. Chill the base in the fridge until very cold, at least an hour.

Churn. Pour the cold base into your ice cream machine and churn until the consistency of a thick smoothie. This takes about 25 minutes in my Cuisinart.

Freeze. Transfer to a container or two, cover well, and freeze for at least four hours before serving.

Oatmeal cookie crumble

Makes 1 1/2 cups

– 1/2 C flour

– 1 C oats

– 1/4 C brown sugar

– 1/4 C cold butter

– 1/2 t salt

– 1 egg

Pulse. In a small food processor, pulse together all ingredients until the mix resembles cornmeal.

Bake. Spread evenly on a parchment covered baking sheet and bake in a 350ºF oven until it starts to brown, about 10 mins. Use 2 forks to break up chunks and return to oven. Bake for about 10 more minutes until golden brown, checking every 2-3 minutes to break up chunks and make sure that the pieces aren’t burnt. Once cool enough to handle, break up chunks until the size of grape nuts.

Store. Store in an airtight container.
