Marshmallows
Adapted From :Baking: From My Home to Yours by Dorie Greenspan
1 cup cornstarch
¾ cup cold water
1 ¼ cups plus 1 tablespoon sugar
2 tablespoons light corn syrup
2 ¼-ounce packets unflavored gelatin
3 large egg whites, at room temperature
1 tablespoon pure vanilla extract
Line a rimmed baking sheet – choose one with a rim that is 1 inch high – with parchment paper and dust the paper generously with potato starch or cornstarch. Have a candy thermometer at hand.
Put 1/3 cup of the water, 1 ¼ cups sugar and the corn syrup in a medium saucepan over medium heat. Bring the mixture to a boil, stirring until the sugar dissolves. Once the sugar is dissolved, continue to cook the syrup – without stirring – until it reaches 265 degrees F on the candy thermometer, about 10 minutes.
While the syrup is cooking, work on the gelatin and egg whites. In a microwave-safe bowl, sprinkle the gelatin over the remaining cold water (a scant 7 tablespoons) and let it sit for about 5 minutes, until it is spongy, then heat the gelatin in a microwave oven for 20 to 30 seconds to liquify it. (Alternatively, you can dissolve the gelatin in a saucepan over low heat.)
Working in the clean, dry bowl of a stand mixer fitted with the whisk attachment, or in another large bowl with a hand mixer, beat the egg whites on medium-high speed until firm but still glossy – don’t overbeat the and have them go dull.
As soon as the syrup reaches 265 degrees F, remove the pan from the heat and, with the mixer on medium speed, add the syrup, pouring it between the spinning beater(s) and the sides of the bowl.Add the gelatin and continue to beat for another 3 minutes, so that the syrup and the gelatin are fully incorporated. Beat in the vanilla.
Using a large rubber spatula, scrape the meringue mixture onto the baking sheet, laying it down close to a short end of the sheet. Then spread it into the corners and continue to spread it out, taking care to keep the height of the batter at 1 inch; you won’t fill the pan. Lift the excess parchment paper up to meet the edge of the batter, then rest something against the paper so that it stays in place (I use custard cups).
Dust the top of the marshmallows with potato starch or cornstarch and let the marshmallows set in a cool, dry place. They’ll need about 3 hours, but they can rest for 12 hours or more.
Once they are cool and set, cut the marshmallows with a pair of scissors or a long thin knife. Whatever you use, you’ll have to rinse and dry it frequently. Have a big bowl with the remaining potato starch or cornstarch at hand and cut the marshmallows as you’d like – into squares, rectangles or even strips (as they’re cut in France). As each piece is cut, drop it into the bowl. When you’ve got 4 or 5 marshmallows in the bowl, reach in with your fingers and turn the marshmallows to coat them with starch, then, one by one, toss the marshmallows from one hand to the other to shake off the excess starch; transfer them to a serving bowl. Cut and coat the rest of the batch.
and here are some variations that Dorie recommends:
Raspberry Marshmallows: Fruit purees are excellent for flavoring these candies. For raspberry marshmallows, you’ll need a generous 1/3 cup of puree; reduce the vanilla extract to ¼ teaspoon. After the batter is mixed, gently fold in the puree with a rubber spatula. You can use the same measurements and technique for other purees, such as strawberry, mango, and passion fruit.
Cappuccino Marshmallows: Sift ¼ cup unsweetened cocoa powder, 2 tablespoons instant espresso powder, and ½ teaspoon ground cinnamon together into a small bowl. Stir in 1/3 cup boiling water and mix until smooth. Reduce the vanilla extract to ½ teaspoon, and add it to the espresso mix. After you add the sugar syrup and gelatin to the meringue, beat in the espresso mixture and continue.
Light Chocolate Marshmallows: Melt 3 ounces bittersweet or semisweet chocolate and stir in 2 ½ tablespoons unsweetened cocoa powder. Reduce the vanilla extract to ¼ teaspoon, and after the marshmallow batter is mixed, fold in the chocolate mixture with a large rubber spatula.
Pumpkin Spice Marshmallows: Whisk together ½ cup canned unsweetened pumpkin puree, 1 teaspoon ground cinnamon, ½ teaspoon ground ginger, a pinch of freshly grated nutmeg and a pinch of ground allspice. After the marshmallow batter is mixed, fold in the spiced pumpkin with a large rubber spatula.
