Homemade Marshmallows

Hey Team-

This is a recipe that I've been wanting to try for a long while, and finally decided to do it.  The recipe that I used was attributed to Thomas Keller, but I cannot confirm this.  Here's how it works:

Ingredients:
3 envelopes of unflavored gelatin
1/2 cup cold water
2 cups granulated sugar
2/3 cups corn syrup
1/4 cup water
1/4 teaspoon salt
1 Tablespoon vanilla extract
Confectioners' sugar

Instructions:
Pour the 1/2 cup cold water into your stand mixer, add the gelatin.  Let this sit for 20 minutes.  It will turn to ugly jello.
In a small saucepan, combine the sugar, corn syrup and 1/4 cup water.  Bring to a full boil and boil for 60 seconds.
Transfer the mixture to your mixer, add the salt, and beat on high (I actually started out on medium for the first 3-4 minutes until the mixture firmed up, to prevent splattering).  In the last minute, add the vanilla.
While that is in the mixer, lightly but thoroughly oil the inside of a 9x9 pan (I actually used a pie pan), and a plastic spatula
Scoop, prod, or otherwise cajole the now very sticky mixture into the pan, and do your best to spread it out evenly (though the peaks and valleys do provide some character)
Let the marshmallow block rest for 12 hours.
Remove the marshmallow block and cover it in confectioner's sugar.  Use scissors or a pizza cutter to cut them into whatever shapes you desire, and cover any newly exposed edges in sugar.
