canning and preserving: freezing swiss chard

Our garden's swiss chard has thrived so much this year that it actually got away from us. We eat a lot of vegetables, but two people can only eat so much in a given week. We hadn't picked any chard in probably three weeks, and in that time the plants got huge, to the point where they were starting to be attacked by pests. 

I decided to harvest it all, in the hopes that we'll get another round later. But this is what I picked from the 5 or 6 plants we have. (OK, plus the peppers, few tomatoes and bag of green beans.) Knowing that you can obviously buy frozen spinach, I decided to try something new and freeze greens at home.


After I took out some chard to make tacos, this is what was left. I separated the leaves and the stems for ease of chopping. Those are decent sized bowls, too.


And then I chopped and I chopped and I chopped.


While I was chopping, I was bringing a large pot of water to boil. Once it was up to temp, I would take batches of leaves and stems and blanch them for about 3 minutes.

Blanching is a quick dunk in boiling water - you can do it with beans and tomatoes, too. It kills the enzymes that make vegetables decay, so they will stop "going bad" in the freezer and retain their color and flavor. I hear you can buy blanchers that are strainer type things that go inside the pots for ease of removal. That would probably be helpful if you're blanching greens like I was, because man those stems and leaves were hard to fish out.

Once they were out, they were dunked straight into a bowl of ice cold water, to bring down the temperature and abruptly stop the blanching process.


Then it was time to squeeze. The soggy chard hung out in a colander until I added another batch and then another, and so on.


After all of the chard was blanched, rinsed and cooled, I picked up handfuls at a time and squeezed as much moisture out as possible. Each ball was placed on a cookie sheet with parchment paper, for the freezer. 


After about 4 hours, the balls were solid and frosty.


Just like the peppers, the swiss chard balls went in a Ziploc bag, with the date as well as a reminder that each ball is about a serving.


Now they'll be ready to defrost and saute when we need them. I'm not sure how well other greens freeze, like collards or kale. But I know that for the recipes and side dishes where we need chard, the frozen balls will be sufficient. 

Theoretically you could remove the stems and only freeze the leaves. I've seen recipes for pickled chard stems, but since I'm not interested in pickling every single vegetable on the planet, and because I love the stems of chard just as much as the leaves, I included them. I just chopped off the most fibrous portions from the bottom and threw them in the compost.

What's going gangbusters in your garden right now? Any preservation plans?

canning and preserving: freezing peppers

This weekend, our backyard harvest was so big that I had to face facts - the peppers were not going to fit in the fridge. So it was time to get to chopping.



I had sweet bell, poblano, hot wax and jalapeno peppers, so I started with the sweet and worked my way up to hot. I cut them into wide pieces - 4 for the larger peppers, and 2 for the small hot peppers.



After pulling out the seeds and pith, I laid them out, skin side up on a cookie sheet with foil.


After a few minutes under the broiler, the skins start to blister and blacken.


I didn't do a great job of capturing the next step on video because my hands were covered in skins, but once the peppers come out of the oven, you can peel off the blistered skin to reveal the roasted pepper flesh underneath. 

I will note that I did use gloves while cutting the hot wax and jalapeno peppers, though they must have had Scoville units off the charts, because I have major hot pepper fingers today. I've had pepper in my eyes before, or on a finger or two, but nothing like this. I am not sure if the peppers being really hot made some of the gloves' protection break down, but all 10 of my fingers - not just the tips - are suffering. Remember that hot peppers can vary in their strength - it's not just habaneros that will burn you. 

*Edit* I did some research and apparently capsaicin can burn through latex gloves, which is why I got hot pepper hands. The safer kinds of gloves are nitrile or rubber dish gloves, though thinking of peeling the skins off of pepper pieces wearing rubber dish gloves is just not at all appealing. 

I laid them on another cookie sheet with a piece of parchment paper on it, making sure that they didn't touch each other, if possible.


Next, the tray goes in the freezer until the pieces are individually frozen. It's the same technique that you use when you want to freeze berries or tomatoes individually, instead of having them be frozen in one massive block. This allows you to pick out individual peppers when you need them, instead of having to defrost the entire batch at once.

After they were completely frozen, I put them in Ziploc freezer bags, marked with the type of pepper.



Now when I need them, I can take a piece out and basically rinse it under hot water to "wake it back up."

This is a great way to preserve peppers, since they are now roasted and ready for sandwiches or other recipes that call for roasted peppers. You can do as many or as few as you have, too, so it doesn't require you to have the right quantity as many canning recipes do.
