Step 7: Time To Set Up
Spray down your spatula with the cooking spray. Now pour and scrape your marshmallows into your powder coated dish. Try to push the mixture into all corners of the dish and then flatten the marshmallows out. You don't have to be too exact, part of the beauty of homemade marshmallows is that they don't all look the same.
Sprinkle the top of the marshmallows with more of your sugar/cornstarch mixture. Let this sit uncovered for at least 4 hours.
Now is an excellent time to lick the bowl, spatula and beaters clean.
