You can see how cleanly the cups turn out if you just keep scraping. Spoiler alert ahead!
I left the sorbet out for about ten minutes before scooping it into the lemons and it started to get a little too runny. I had to put the cups into the freezer as soon as they were done and forgot to get an after picture. So, instead I have the final picture from the bridal shower. You can see that I filled the cups with sorbet and then just used my finger to smooth out the tops (with clean hands of course!). I returned the cups to the freezer until it was time to serve!
I ended up buying the sorbet to make my life easier, but you certainly could make it yourself. This idea would work with tons of flavors and was so fun. It also worked great ahead of time, so I would recommend it to anyone!
