I didn't blanch the kale and other greens in hot water before freezing them. I hope it's not too late to do it now. I'll try. I read this on a blog, I guess it's how you should do it...
• Put on a big pot of water to boil.
• Wash kale in sink of water then drain in a second sink or on a towel on the counter top.
• Tear or cut into 2 inch strips or manageable sizes (I did not freeze the big thick stems from the curly kale but smaller stems are ok).
• Fill sink with clean cold water, including as many ice cubes as you have on hand.
• Place the cut kale in boiling water and boil for 3 minutes.
• Take kale out of pot with tongs, a colander, and/or slotted spoon.
• Put hot kale in cold water and swish around.
• Take kale out of water.
• Drain any excess water off greens (save for future soup broth!).
• Measure either 2 cups or 4 cups and place into freezer bags.
• Mark freezer bag with date and type of greens.
• Press any excess air out of bag and freeze.
I'm new to home farming, and I don't really know how to save food. I'm really just learning.
