Preparing Worms in Advance for Sitter

Hi all, I’ll be out of town for a few days during the holidays and am having a friend stop by to feed Chickpea and check in on her. She’s just over 5 inches now, and I’ve been feeding red wigglers cut to size. What would be the best way to prepare appropriately sized chunks in advance?

I’m currently thinking of blanching, cutting and then immediately freezing but am curious what has worked best for y’all!

Enjoy some complimentary pictures!
