Marshmallows
via Make The Bread, Buy The Butter
Three 1/4-ounce packets unflavored gelatin
1 1/2 cups granulated sugar
1 cup light corn syrup
2 egg whites
2 teaspoons vanilla extract
1/4 cup cornstarch
1/4 cup confectioner's sugar
In a tiny saucepan, over low heat, dissolve the gelatin in 7 tablespoons of water. It will be pale beige and viscous. Turn off the heat.
In a larger saucepan, heat the granulated sugar and corn syrup with 1/2 cup water.
Bring to a boil, stirring until dissolved. Let it boil until it registers 265 F on a candy thermometer.
Meanwhile, in the bowl of a mixer, begin whisking the egg whites. Beat until firm and glossy. As soon as the sugar syrup registers 265 F, begin pouring it in a slow steady stream into the egg whites, beating constantly. Add the gelatin and continue beating. When you start, the hot liquid will slosh around the bowl and you will think it is hopeless; by the time you are done, the mixture will have swollen into a luxuriant white cloud. Whisk until the bowl is cool to the touch.
Whisk in the vanilla.
Lightly grease a rimmed cookie sheet. Mix together the cornstarch and confectioner's sugar and sift half onto the cookie sheet. You want a really generous bed of powder. On top of this, spread the marshmallow and smooth the top. Let sit overnight.
In the morning, cut the marshmallows into 36 pieces with a sharp knife. If they stick, dip the knife in water. (Damp scissors can also help with the job.) Toss the marshmallows in the leftover powder; you want all the exposed sides of the marshmallows to be lightly coated in powder, which will keep them from sticking to each other.
Store in a cookie tin or resealable plastic bag. They keep indefinitely, though they become crustier and less appealing after a week or so.
