Fluffy Lemon-Strawberry Marshmallows

Ingredients

1 cup water, divided2½ tablespoons unflavored gelatin 2 large egg whites 2 cups (14 ounces/397 grams) granulated sugar ½ cup light corn syrup ¼ teaspooon table salt ½ ounce (14 grams/1 cup) freeze-dried strawberries, ground to powder1 tablespoons vanilla extract 1 tablespoons grated lemon zest ⅔ cup (2⅔ ounces/76 grams) confectioners' sugar ⅓ cup (1⅓ ounces/38 grams) cornstarch

Before You Begin

Three ¼-ounce envelopes of gelatin will yield the 2½ tablespoons needed for this recipe. You will need a candy thermometer or another thermometer, such as an instant-read probe model, that registers high temperatures for this recipe. For a cleaner look, you can trim (and snack on) the edges of the marshmallows before cutting them into squares. Grind the strawberries to a powder in a spice grinder.

Instructions

  1.  Make foil sling for 13 by 9-inch baking pan by folding 2 long sheets of aluminum foil; first sheet should be 13 inches wide and second sheet should be 9 inches wide. Lay sheets of foil in pan perpendicular to each other, with extra foil hanging over edges of pan. Push foil into corners and up sides of pan, smoothing foil flush to pan. Spray pan with vegetable oil spray.
  2.  Whisk ½ cup water and gelatin together in bowl and let sit until very firm, about 5 minutes. Add egg whites to bowl of stand mixer fitted with whisk attachment.
  3.  Combine granulated sugar, corn syrup, salt, and remaining ½ cup water in large saucepan. Bring to boil over medium-high heat and cook, gently swirling saucepan occasionally, until sugar has dissolved completely and mixture registers 240 degrees, 6 to 8 minutes. Off heat, immediately whisk in gelatin mixture until gelatin is dissolved.
  4.  Working quickly, whip whites on high speed until soft peaks form, 1 to 2 minutes. With mixer running, carefully pour hot syrup into whites, avoiding whisk and bowl as much as possible. Whip until mixture is very thick and stiff and bowl is only slightly warm to touch, about 10 minutes. Reduce speed to low and add strawberry powder and vanilla. Slowly increase speed to high and mix until incorporated, about 30 seconds, scraping down bowl as needed. Stir in lemon zest with rubber spatula.
  5.  Transfer mixture to prepared pan and spread into even layer using greased rubber spatula. Let sit at room temperature until firm, at least 4 hours.
  6.  Lightly coat chef's knife with oil spray. Whisk confectioners’ sugar and cornstarch together in bowl. Lightly dust top of marshmallows with 2 tablespoons confectioners’ sugar mixture. Transfer remaining confectioners’ sugar mixture to 1-gallon zipper-lock bag. Place cutting board over pan of marshmallows and carefully invert pan and board. Remove pan and peel off foil.
  7.  Cut marshmallows crosswise into 8 strips, then cut each strip into 6 squares (marshmallows will be approximate 1½-inch squares). Separate marshmallows and add half to confectioners’ sugar mixture in bag. Seal bag and shake to coat marshmallows.
  8.  Using your hands, remove marshmallows from bag and transfer to colander. Shake colander to remove excess confectioners’ sugar mixture. Repeat with remaining marshmallows. Marshmallows can be stored in zipper-lock bag or airtight container at room temperature for up to 2 weeks.

Why This Recipe Works

For a homemade gift that's sure to impress, try marshmallows. These marshmallows are lighter and fluffier than store-bought varieties, thanks to the addition of egg whites. To make them, we cooked sugar, corn syrup, water, and salt until the mixture reached the soft-ball stage and then stirred in some bloomed gelatin until it dissolved. Then we whipped egg whites to soft peaks in a stand mixer, streamed in the hot sugar syrup, and watched the mixture transform from sloshy to fluffy as it whipped. Once we had whipped the mixture until it was cooled and stiff, we stirred in vanilla, strawberry powder, and lemon zest and spread it in a greased and lined pan and let it set. We cut the set marshmallows into squares and tossed them in a confectioners’ sugar–cornstarch mixture to coat them, using a zipper-lock bag to speed up the process and contain the mess.
