These were AWESOME freshly coated in sugar. Mmmmm...such a good little snack.
These were not so awesome after freezing or a few days later. Make them the day you want them and have them eaten that day or the next.
I marinated my grapes overnight. Seriously...delicious fresh, so marinate them the day before you want to serve them and then just coat them in the sugar the day of.
Wonderfully easy grown up snack.
