  1. Hi Sara, thanks for your delicious article 🙂

    I used to freeze kale from our garden like you do spinach, but I left the stems on the leaves. Then when I wanted to use them in my green smoothies, I took a leaf or two (they were pretty big), and when the leaf was frozen, the stem was easy to remove.

    This method works well even if you would like to use the kale leaves for cooking. It is very easy to crumble them when they’re still frozen!

    Happy blending!
