THE CROSS SECTION PICTURE!!!
3 packages unflavored gelatin
1 1/2 cups granulated sugar
1 cup light corn syrup
1/4 teaspoon kosher salt
1 tablespoon pure vanilla extract
Confectioners’ sugar, for dusting
Combine the gelatin and 1/2 cup of cold water in the bowl of an electric mixer fitted with the whisk attachment and allow to sit while you make the syrup.
Meanwhile, combine the sugar, corn syrup, salt, and 1/2 cup water in a small saucepan and cook over medium heat until the sugar dissolves. Raise the heat to high and cook until the syrup reaches 240 degrees F on a candy thermometer. Remove from the heat.
With the mixer on low speed, slowly pour the sugar syrup into the dissolved gelatin. Put the mixer on high speed and whip until the mixture is very thick, about 15 minutes. Add the vanilla and mix thoroughly.
Pour the marshmallow batter in an 9 by 13- pyrex that has been greased and dusted generously with confectioners sugar. Smooth the top of the mixture with damp hands. Allow to dry uncovered at room temperature overnight. Cut with cutters into squares or circles and use same cutter for the graham crackers. Dust with more confectioners sugar.
