Hydrate Gelatin
1 Whisk 40 grams of gelatin and 230 grams of cold water in the bottom of your 5 quart mixing bowl.  Set aside to hydrate while you cook your syrup.
Cooking Syrup
2 In a heavy duty thick bottomed pot, combine 680 grams sugar, 560 grams corn syrup, and 170 grams of water.  Heat over high heat, stirring constantly, until 252F.
3 Remove from heat. Cool until 210F, undisturbed.
Making Marshmallows
