Invertase
Posted in: Tech Help, Tips, Tricks, Techniques
I am not an expert, but my understanding is that the ratio of invertase to fondant should range between .1-.3%. The larger amount will make the process speed up a bit. So for a pound of fondant (454 grams), you would want to use .5 to 1.5 grams of invertase. I'm guessing this is about 1/4 tsp, but you should of course do things like this by weight not volume.
As for keeping it cold, I don't think so. You want to make sure you don't add the invertase into a fondant mixture that is too hot (nothing over 150F), but once the final pieces have been dipped storing them at a cold temperature actually slows down the process. So if you want to move the process along keep them at the same general room temp you keep your other confections. Others here with more experience may have more (or better) info however.
