Frequently Asked Questions
Food Safety
- Can I thaw meat or poultry on the kitchen counter?
- NO. The safest way to thaw meat or poultry is to take
it out of the freezer and leave it overnight in the
refrigerator. Normally , it will be thawed ready to use the next day.
For faster thawing, put the frozen package in a watertight plastic
bag under cold water. Change the water every 15 - 20 minutes to maintain
the cold temperature. You may, also, thaw meat and poultry in the
microwave oven. Follow the manufacturer's directions.
- Is it safe to just put the large kettle of
chili or soup in the refrigerator to cool?
- NO. Foods should be placed in shallow
containers making the food less than two inches deep for even and fast
cooling. Foods in deep containers will cool at the outer edges first
leaving the center hot enough long enough for bacteria to grow.
- Is it safe to use raw eggs in dishes?
- NO. Eggs should be cooked. Avoid eating
raw eggs and foods containing raw eggs, i.e. homemade products such
as eggnog, ice cream, Caesar salad dressing, hollandaise sauce, cream
pies, etc.
- How long is it safe to leave foods out of the
refrigerator?
- Observe the two hour rule. Foods should
not be at room temperature longer than two hours before refrigerating.
In hot weather, foods should never sit out for more than an hour.
- My power has been off, what food is still safe
in my freezer?
- Ordinarily, a fully stocked freezer
will keep food frozen for 2 days after losing power. A half-full freezer
can maintain freezing power for roughly 1 day. To know what food is
still safe, you must check the food in freezer as soon as the power
comes back on. Meat or poultry that still contain ice crystals may safely
be refrozen. For meat or poultry that have thawed but remained "cool-feeling" (below
40F), cooking is recommended, then you may freeze the cooked meat. For
frozen vegetables, refreeze, only if ice crystals are still present
or if the freezer temperature is 40F or below. For fruits, refreeze
if they show no signs of spoilage. Thawed fruits may be used in cooking
or making jellies, jams or preserves.
Food Preservation
- Is it safe to can food without salt?
- Yes. Salt is used for
flavor and is not necessary to prevent spoilage.
- Is it safe to can green beans in a boiling
water bath if vinegar is used?
- NO. The only safe process
for canning green beans, a low acid food, is the pressure canner
method.
- Is it safe to can fruits without sugar?
- Yes. Sugar is added
to improve flavor, help stabilize color, and retain the shape of
the fruit. It is not
added
as a preservative.
- Can food be recanned if the lid does not
seal?
- Canned food can safely
be recanned if the unsealed jar is discovered within 24 hours. To
recan, remove
the lid and check the jar sealing surface for tiny nicks. Change
the jar if necessary, add a new treated lid and reprocess using the
same
processing time.
- If my recipe doesn't call for processing,
do I need to do so?
- Yes. Canning recipes
prior to 1990 should not be used. Many old recipes do not include
instructions for
processing foods. The foods are canned by the open kettle method,
sealed and stored. This method for canning, the open kettle method,
is not recommended for it presents a serious
food safety hazard.
All high acid foods should be processed in a water bath canner and
all low acid foods in a pressure canner.
- Why is open kettle canning not recommended?
- In open kettle canning,
food is cooked in an ordinary kettle, then packed into hot jars and
sealed with processing.
The temperatures obtained in open kettle canning are not high enough
to destroy all spoilage and food poisoning organisms that may be
in the food. Also, microorganisms can enter the food when it is transferred
from the kettle to jar and cause spoilage.
- How long will home canned foods keep?
- Properly canned food
stored in a cool, dry place will retain optimum eating quality for one year.
- Is it safe to process foods in the oven?
- NO. This can be dangerous
because the temperature will vary according to the accuracy of oven
regulators
and
circulation of heat. Jars explode easily in the oven.
- Why do the underside of metal lids sometimes
discolor?
- Natural compounds in
some foods, particularly acids, corrode metal and make a dark deposit
on the underside of jar
lids. This deposit on lids of sealed, properly processed canned
foods is harmless.
- Why do foods darken in the top of jars?
- Liquid did not cover
food or food was not processed long enough to destroy enzymes.
- Why is there sometimes a loss of liquid
during processing?
- Loss of liquid may be
due to the fluctuating pressure in the pressure canner, food packed
too tightly in jars or
lowering pressure too suddenly. At the end of processing time,
allow the pressure to drop to zero naturally and wait two to five
minutes
before opening the lid.
- What causes fruit to float in jar?
- Fruit is lighter than
the syrup. Pack fruit tightly in jar, but do not crush it. Use a
light syrup.
- Can I use flaked salt for pickling?
- Most recipes call for
granulated pickling salt or canning salt. Flake salt varies in density
and is not recommended
for pickling,
- I don't have the type of dill my recipe
calls for. How can I substitute what I have?
- For each quart try 3
heads of fresh dill or one tablespoon dill seed.
- Can I use burpless cucumbers for pickling?
- Burpless cucumbers are
not recommended for use in fermented pickles. This is because at
their normal mature
size, they produce a softening enzyme that causes the pickles to
soften during fermentation.
- Why did the garlic cloves in my pickles
turn green or bluish green?
- This reaction may be
due to iron, tin or aluminum in your cooking pot, water or water
pipes reacting
with
the pigments in the garlic. Or, the garlic may naturally have more
bluish pigment and it is more evident after pickling . The pickles
are safe
to eat.
- Why are my pickles soft?
- Any of the following
may cause soft pickles: failure to remove the blossom end of the
cucumber, cucumbers
are exposed above the brine, vinegar or brine is too weak, or pickles
were precooked at too high temperature (overcooked).
- Should jelly be boiled slowly or rapidly?
- Jelly should be boiled
rapidly since long, slow boiling destroys the pectin in the fruit
juice.
- Can I make a double batch of jelly?
- NO. If a larger quantity
of juice is used, it will be necessary to boil it longer thus causing
loss of
flavor,
darkening of jelly, and toughening of jelly.
- Why is my jelly soft?
- The following can cause
soft jelly: overcooking the fruit to extract the juice, using too
much water to
extract the juice, incorrect proportions of sugar and juice, undercooking
causing insufficient concentration, insufficient acid, or making
too large a batch at one time.
- What is blanching?
- Heating or scalding
vegetables in boiling water or steam for a short period of time.
- Is it recommended to blanch vegetable before
freezing?
- YES. Blanching slows
or stops the action of enzymes which cause loss of flavor, color
and texture. Blanching
cleanses the surface of dirt and organisms, brightens the color
and helps retard loss of vitamins. Blanching also wilts or softens
vegetable
and makes them easier to pack.
- Why is it necessary to cool vegetables
after blanching?
- Vegetables should be
cooked quickly and thoroughly after blanching to stop the cooking
process. Otherwise,
vegetables will be overcooked with loss of flavor, color, vitamins
and
minerals.
- Can I blanch in my microwave oven?
- Microwave blanching
may not be effective, since research has shown that some enzymes
may not be inactivated.
Stain Removal
- How can I get ball point ink out of a shirt?
- Place stain face down on white paper
towels. Sponge stain with rubbing or denatured alcohol or hair spray.
Rub detergent into stained area. Launder.
- How do I remove candle wax from carpet?
- Apply ice cubes to stain. Remove surface
wax with dull knife. Place paper towels or brown paper on top of
stain. Press very lightly with a warm iron. Change paper towels
or brown paper
as they absorb the wax. Rinse stain with white vinegar and water
solution.
- Help-I washed a crayon with a load of laundry.
How can I remove the stains?
- If you catch it before the clothes
go in the dryer there is hope. If the clothes have been dried in
a clothes
dryer, the stains are set. To remove crayon stains from a load of
laundry, wash with hot water, and 1 cup of laundry soap (not detergent),
plus
1 cup of baking soda. If stain remains, launder again with detergent
and chlorine bleach, if safe for fabric. If fabric is not chlorine
bleached
safe, soak in hot water with an oxygen bleach or prewash enzyme solution.
Launder.
- How can I remove mildew stains from a table
cloth?
- Rub liquid detergent into dampened
stain. Launder, using hot water, detergent and chlorine bleach ,
is safe for fabric. If stain remains, sponge with hydrogen peroxide.
Rinse
and relaunder. Dry in the sunlight.
