What is the most efficient way to squeeze water out of cooked spinach? I'm cooking a bunch of spinach for making a spinach and ricotta filling. I need to get as much water as possible out of the spinach, and I'd prefer not to make a big mess in the process. In the past, I've wrapped a few handfuls at a time in a towel and squeezed out the liquid. This leaves me with a messy, green stained towel and requires a lot of twisting that doesn't seem maximally effective.
Use a potato ricer. Just fill it up with a big handful of spinach, and give it a good squeeze in the sink, or over a bowl if you like to drink spinach water. It extracts a ton of liquid quickly, and is a breeze to clean up when you are done.
