Homemade Marshmallows

Homemade Marshmallows (from here)

Notes: I made these today, and I fell in love. They are so soft and delicious. I reconstituted meringue powder (and beat them to stiff peaks by hand since the marshmallow mix was already in the Kitchen Aid). I think those are all the notes I had. I didn't have any other modifications. I did use vanilla extract as the recipe says.

Springy, Fluffy Marshmallows
Adapted from Gourmet, December 1998

These homemade marshmallows are not only easy to make, they set as perfectly as promised: puffed and lightweight, bouncing off one another as I tossed them in the container. Even better, they toasted like a campfire charm speared on the end of a skewer, and s’mooshed between two graham crackers with a square of chocolate.

Makes about 96 1-inch cubed marshmallows

About 1 cup confectioners’ sugar
3 1/2 envelopes (2 tablespoons plus 2 1/2 teaspoons) unflavored gelatin
1 cup cold water, divided
2 cups granulated sugar (cane sugar worked just fine)
1/2 cup light corn syrup
1/4 teaspoon salt
2 large egg whites or reconstituted powdered egg whites
1 tablespoon vanilla (alternately: 1/2 of a scraped vanilla bean, 2 teaspoons almond or mint extract or maybe even some food coloring for tinting)

Oil bottom and sides of a 13- by 9- by 2-inch rectangular metal baking pan and dust bottom and sides with some confectioners’ sugar.

In bowl of a standing electric mixer or in a large bowl sprinkle gelatin over 1/2 cup cold cold water, and let stand to soften.

In a 3-quart heavy saucepan cook granulated sugar, corn syrup, second 1/2 cup of cold water, and salt over low heat, stirring with a wooden spoon, until sugar is dissolved. Increase heat to moderate and boil mixture, without stirring, until a candy or digital thermometer registers 240°F, about 12 minutes. Remove pan from heat and pour sugar mixture over gelatin mixture, stirring until gelatin is dissolved.

With standing or a hand-held electric mixer beat mixture on high speed until white, thick, and nearly tripled in volume, about six minutes if using standing mixer or about 10 minutes if using hand-held mixer. (Some reviewers felt this took even longer with a hand mixer, but still eventually whipped up nicely.)

In separate medium bowl with cleaned beaters beat egg whites (or reconstituted powdered whites) until they just hold stiff peaks. Beat whites and vanilla (or your choice of flavoring) into sugar mixture until just combined. Pour mixture into baking pan and don’t fret if you don’t get it all out (learning from my mess of a first round). Sift 1/4 cup confectioners sugar evenly over top. Chill marshmallow, uncovered, until firm, at least three hours, and up to one day.

Run a thin knife around edges of pan and invert pan onto a large cutting board. Lifting up one corner of inverted pan, with fingers loosen marshmallow and ease onto cutting board. With a large knife trim edges of marshmallow and cut marshmallow into roughly one-inch cubes. (An oiled pizza cutter works well here too.) Sift remaining confectioners’ sugar back into your now-empty baking pan, and roll the marshmallows through it, on all six sides, before shaking off the excess and packing them away.

Do ahead: Marshmallows keep in an airtight container at cool room temperature 1 week.
