How to Use Low Temperature Pasteurization for Pickles

We recently hosted a canning class taught by Marisa McClellan of Food in Jars. The hands-on canning class, at Fillmore Container, focused on low temperature pasteurization. For those of you that are following along with the Food in Jars Mastery Challenge, this month’s challenge is all about Low-Temperature Pasteurization.

What is low-temperature pasteurization?

It is a preservation technique in which you simmer your filled jars in water that’s between 180 and 185 degrees F. You do this for a longer period of time than you would normally process them in a boiling water bath canner. The longer, lower temperature allows you to kill off bacteria while achieving the goal of retaining a firmer texture pickle. Here’s the basics of the preserving method along with the pickle recipe that we made during the class.

Why use low-temperature pasteurization?

Have you ever made a batch of pickles with the highest of hopes, only to open up the jars in October or November and find flavorful but soft, soggy slices or spears? If this is something you’ve experienced, you probably found yourself wondering, “How can I make crunchy, shelf-stable pickles?” If that sounds familiar, then low-temperature pasteurization may be for you!

What do I need?

All you need to try out this style of preserving is a canning pot, an adjustable heat source, and a reliable thermometer. You may need to practice a little to figure out how to get your water to maintain the proper temperature. However, once you do, you’ll be rewarded with crisp, snappy pickles! To find out more about this method read this post.

RECIPE
Garlic Dill Pickles

Yield: 10 pintsPreparing jars

Ingredients

6 pounds pickling cucumbers
3 cups apple cider vinegar
3 cups water
3 tablespoons pickling salt
1 teaspoon dill seed per jar
1 teaspoon peppercorns per jar
1 teaspoon mustard seeds per jar
1-2 garlic cloves per jar

Prepare a low-temperature pasteurization pot and 10 pint jars.

Wash cucumbers well. Trim away the blossom end, which is a very important step. While trimming the cucumbers may seem wasteful, there’s an enzyme (pectinase) that will cause your pickles to become soft. Trim about 1/16 inch from that blossom end before pickling. After trimming, cut cucumbers into halves, spears, or coins.

Combine the apple cider vinegar, water, and pickling salt in a saucepan or 4th burner pot (rack removed) and bring to a boil. (Read more about our versatile 4th burner pot here.)

Portion the spices and garlic cloves into the prepared jars. Pack the cucumbers into the jars and add the brine, leaving 1/2 inch headspace.pouring pickling brine

Using a wooden chopstick, wiggle out any trapped air bubbles, and add more brine, if necessary.

Wipe the rims, apply the lids and rings, and process in a boiling water bath canner or in a low temperature pasteurization pot for 25 minutes at 180F.  Note the thermometer clipped on the water bath canner in photo below.

When the time is up, remove the jars and set them on a folded kitchen towel to cool.

When the jars have cooled enough that you can comfortable handle them, check the seals. Sealed jars can be stored at room temperature for up to a year. Any unsealed jars should be refrigerated and used promptly.

    I have to say that in my opinion,the best way to get a crispy crunchy pickle is using the pickling lime method.Doesn’t matter if it’s a sweet cucumber pickle or any kind of dill…as long as you follow the direction with the pickling lime,which is usually soaking your product in the lime solution,rinsing and going forward with your brine,spices,garlic,sugar…whatever you choose for flavor…you are guaranteed a crisp and crunchy pickle…processing time is the same as with any pickle product.I have even made sweet green tomatoe pickles this way…crisp as can be.At any rate,this is how I make mine,and have never been disappointed.Just thought I’d pass that on.

    If I do not wish to use vinegar, only water, salt and spices to do a Lacto Fermented process, will warming the water in the jars and following your suggests above work for Lacto Fermented pickles

      This would be a very different process. I’d refer you to Amanda Feifer of Phickle (www.phickle.com) for the lacto fermented pickling questions.

    Sounds good. I’m going to try this. Two questions:
    1. I assume you don’t put the jars in the pot until the temperature is right. When you do, do you need to wait until it comes back to 180, or do you start timing right away?
    2. Can this be adapted for quart jars?

    Thanks, Tom

      Hi Tom, You are correct….you want to have the water at least at 180 before you put the filled jars in. Because the jars will lower the temperature, it’s helpful to have the water a little hotter than the 180. Yes, you wait until the temp of 180 is reached before starting your timer. In addition, if it goes below the 180, you need to start over after bringing it back up to the 180.
