Sweets | Lemon & Blueberry Frozen Yogurt
Posted on June 9, 2013
Jeni's ice creams are always really good. This time I tried a frozen yogurt, it was creamy and super yummy.
Yield: 2 pints / 1 quart
FROZEN YOGURT BASE
1 quart plain low-fat yogurt
1 1/2 cups whole milk
2 tablespoons cornstarch
2 ounces (4 tablespoons) cream cheese, softened
1/2 cup heavy cream
2/3 cup sugar
1/4 cup light corn syrup
zest from 1 lemon
2 to 3 lemons
3 tablespoons sugar
1 1/2 cups blueberries
3/4 cup sugar
Mix the blueberries and sugar in a small saucepan and bring to a boil over medium heat. Reduce the heat and simmer, stirring occassionally, until the berries are tender and the sauce is thickened about 8 minutes. Remove from the heat and let cool, then refrigerate until cold before using.
LEMON & BLUEBERRY FROZEN YOGURT
For the frozen yogurt base:
Fit a sieve over a bowl and line it with two layers of cheesecloth. Pour the yogurt into the sieve, cover with plastic wrap, and refrigerate for 6 to 8 hours to drain. Discard the liquid, and measure out 1 1/4 cups of the drained yogurt; set aside.
For the lemon syrup:
Using a vegetable peeler, remove the zest in large strips from 1 lemon; reserve for the frozen yogurt (leave the lemon zest in large strips so it's easier to strain out later). Juice enough of the lemons to make 1/2 cup.
Combine the lemon juice and sugar in a small saucepan and bring to a boil over medium-high heat, stirring to dissolve the sugar. Remove from the heat and let cool.
For the frozen yogurt base:
Mix about 2 tablespoons of the milk with the cornstarch in a small bowl to make a smooth slurry.
Whisk the cream cheese in a medium bowl until smooth. (I couldn't get this to whisk, I smashed it with a wooden spoon instead.)
Fill a large bowl with ice and water.
Combine the remaining milk, the cream, sugar, corn syrup, and lemon zest in a 4-quart saucepan, bring to a rolling boil over medium-high heat, and boil for 4 minutes. Remove from the heat and gradually whisk in the cornstarch slurry.
Bring the mixture back to a boil over medium-high heat and cook, stirring with a heatproof spatula, until slightly thickened, about 1 minute. Remove from the heat.
Gradually whisk the hot milk mixture into the cream cheese until smooth. Add the reserved 1 1/4 cups yogurt and the lemon syrup and whisk until smooth.
Pour the mixture into a 1-gallon Ziploc freezer bag and submerge the sealed bag in the ice bath. Let stand, adding more ice as necessary, until cold, about 30 minutes.
Remove the zest from the frozen yogurt base. (The yogurt base was too thick to strain out the zest, I suggest you do it prior to chilling phase.) Pour into the frozen canister and spin until thick and creamy.
As you pack the frozen yogurt into storage containers, alternate it with layers of blueberry sauce. Press a sheet of parchment directly against the surface, and seal with an airtight lid. Freeze in the coldest part of your freezer until firm, at least 4 hours.
