Preserving Spring Greens

It feels like spring! But the calendar hasn’t quite caught up to that season yet. Soon, gardeners will be digging in their garden plots to plant early spring produce. Spring greens, such as spinach, are popular. But once it is grown and ready to harvest, how can spring greens be preserved? Here are some options from the National Center for Home Food Preservation:

  • Canning – includes spinach, collards, kale, and others
  • Freezing – gives the best quality product
  • Dehydrating – see page 10

Always choose freshly harvested greens. Discard wilted, discolored, diseased or insect-damaged leaves.

Preserving Horseradish

It’s time to harvest horseradish!

So how can horseradish be preserved? There are no canning instructions, but it can be pickled and stored in the refrigerator. Vinegar helps to tame the strong flavor. The National Center for Home Food Preservation has a recipe for Pickled Horseradish Sauce. Remember, this is stored in the refrigerator only.

The heat and pungency in horseradish comes from the compound allyl isothiocyanate, a mustard-like oil. Vinegar tames this compound, but timing matters! Waiting longer after grinding to add vinegar, the hotter it will be! Learn more from Penn State Extension.

Horseradish can be dried. Clean and peel roots. Grate or slice into 1/4-inch pieces. No blanching is required. Spread on dehydrator trays in a single layer. Dry at 140°F for 6-10 hours until very brittle. Grind into a powder or leave as pieces. To use, mix with a little water before adding to recipes.

It’s Cranberry Season!

Are you still wanting to do some canning? This time of year, cranberries are in season. So here are some recipes from the National Center for Home Food Preservation to preserve cranberries for your own use, or for gift giving.

The berries should be brightly colored: fully red or yellowish-red with a smooth, glossy and firm skin. Shriveled, soft, wrinkled berries or those with surface blemishes should be discarded. Berries can be stored in the original packaging in the refrigerator crisper for up to 4 weeks. Cranberries can also be stored frozen for up to one year. To use after freezing, rinse in cold water and drain well.

 

Is It Safe to Re-can Already Canned Food?

People often think that they can save money by buying larger containers of canned food, transferring the contents (or leftovers from the first use) to smaller jars and re-processing it. Others wonder if this is a way to save leftovers from any size can for a longer time than they will keep in the refrigerator.

There are three main problems with doing this:

  1. There are no safe tested process to do this. The way heat goes through a jar of already canned food is different than fresh food. The food will become very soft and compact more. This could lead to underprocessing and spoilage.
  2. There is no cost savings in re-canning foods.
  3. The food quality will be greatly reduced. Nutrients will be lost and more textural changes will occur.

Bottom line, do not plan to re-can any food.

Cleaning and Storing Canners

As canning season winds down, it’s time to clean and store the equipment for next year. Here’s some tips for pressure canners.

  • Clean the vent and safety valve with a pipe cleaner or small piece of cloth.
  • Check the gasket for cracks and food debris.
  • If the inside of canner has darkened, fill it above the darkened line with at mixture of 1 tablespoon cream of tartar to each quart of water. Place the canner on the stove, heat water to a boil, and boil covered until the dark deposits disappear. Sometimes stubborn deposits may require the addition of more cream of tartar. Empty the canner and wash it with hot soapy water, rinse and dry.

Fall Canning Tips

At this writing, the calendar still says summer, but fall is in the air. Gardens may still be producing, so here are some end-of-season tips for food preservation.

 

Preserve the Best Tomatoes

TomatoesWhen preserving any food, use the best food possible for the safest results. This includes tomatoes. During the fall, many gardeners still have tomatoes on the vines. But once a frost or freeze happens, these tomatoes are not safe to preserve by canning.

When tomatoes are left on the vine towards the end of the growing season, the pH increases above 4.6. This is the dividing point whether a food is a high acid or low acid food. When the pH is above 4.6, it is a low acid food. These tomatoes are also more susceptible to other microbial damage. Tomatoes that have signs of blight or other fungus related infestations have a higher pH making them a low acid food. All of these are not safe for canning.
