First wash the greens really well.
Then cut out the vein in the center
and chop into smaller pieces. You can see I have a lot.
Working in batches, submerge the kale into boiling water and let it boil for about 3 minutes.
Then immediately put into ice water for 3 minutes. You'll have to continue to add ice throughout the process, especially if you have a lot of greens so it's good to make sure you have plenty made ahead of time.
Drain the water from the kale.
Let it sit on a paper towel to get excess water out.
