Pickles should not be kept on your pantry shelf unless they
are canned. This involves heating jars of pickles to temperatures
high enough to kill off spoilage microbesa method known
as heat processing. An airtight vacuum seal forms when
the jars cool, shutting microbes out. Once canned, most pickles
keep for up to one year.

| How
to Prepare Jars and Lids |
. |
Before
use, wash jars in hot, soapy water and rinse thoroughly. Then put
the clean jars on the wire rack inside the boiling-water canner. Fill
with water and bring to a boil. Turn down the heat to keep the water
below simmering. Keep the jars in the hot water until you fill them
with pickles. If the recipe calls for presterilized jars, boil the
jars completely submerged in water for 10 minutes before turning down
the heat.
In a separate small container, heat the lids (flat discs) in hot,
but not boiling water. (NOTE: Some lids have different preparation
steps, so closely follow the lid manufacturers directions.)
Heating softens the sealing compound, helping it form an airtight
seal with the jar. It is not necessary to heat the screwbands because
they never come in contact with the food.
|
| Filling
the Jars |
. |
When you fill the hot jars with your prepared recipe, use a clean,
damp towel to wipe the rims right before applying the lid. Any residue
can prevent the lids from sealing properly.
|
| What
Do I Need? |
. |
|
glass canning jars (often called mason jars) and 2-piece metal canning
lids (see individual recipes to find out how many you need) |
Tip
Many supermarkets, hardware stores, and department stores carry canning
supplies.
Tip
Glass canning jars have two-piece closures. One piece is a flat disk
with a gasket around the rim. The other is a screwband that holds
down the lid against the top of the jar. The band can be reused, but
the lid cannot. |
|
a canner: a large, deep, stainless-steel, nonreactive pot with a tight-fitting
lid (should be large enough to allow at least 4 inches of headroom
above the jars) |
| a
wire basket or rack to fit inside the canner and hold jars |
| a
jar lifter (special tongs) |
|
hot pads or several towels |
|
a timer |

|
| General
Heat-Processing Instructions |
|
|
1.
Place
the closed jars (filled with the prepared recipe) on the wire rack
in the canner, and transfer the jars to the canner (the water in
the canner should still be hot from preparing the jars). Make sure
the water covers the jars by at least 1 inch.

Tip

of Agriculture has guidelines
for safe home canning.

2.
Cover
the canner tightly and bring the water to a rolling boil. When theres
a full rolling boil, start the timer. Reduce the heat to a simmer
and start the timer. Boil the jars for the amount of time recommended
in the recipe.
|
| |
|
3.
When
processing time is complete, remove the lid and turn off the heat.
Use a jar lifter to remove the jars from the canner, and set the
jars upright on a rack or a layer of towels to cool. Make sure to
leave room around the jars for air circulation. Also make sure the
room is draft-free.
|
| |
|
4.
Allow
jars to cool undisturbed for 24 hours. During cooling, you might
hear a soft "ping" when the lids seal tightly. Once the
jars are cool, test for vacuum seals by tapping the top of the jar
with a spoon. You should hear a bell-like tone, not a "clunk."
Also, the lids should be concave; a convex lid is a sign of a bad
seal. Finally, the lids should not move when you press on them with
your finger.
|
| |
|
5.
Refrigerate
the jars that did not seal properly. (Resealing jars after they
have cooled isnt safe.)
|
| |
|
6.
Store
the jars of canned pickles in a cool, dark place, such as a cupboard
or a basement. Eat them within 1 year. Once the jar has been opened,
keep it in the refrigerator.
