Teacher Steps to Boiling Water Canning Grape Jelly
There are many ways to organize work environments for canning. If you are familiar with canning, and
organizing differently, feel free to adjust to your class. It is a good idea to have everyone wear gloves to this
in a class environment.
Work Stations (and supplies needed):
A. Measuring Station
Measuring cups, spoons, bowls, ingredients
B. Canning Jar Preparation Station
9 half-pint canning jars, 9 2-piece canning lids and rings, dish soap, dish pan, paper towels or clean
kitchen towel for drying
C. Jelly Preparation Station
Large saucepot, pre-measured ingredients, pectin, large wooden spoon, metal spoon
D. Jar Filling Station and Placement Into Canner
Trivet for hot saucepot, cake pan to catch drips, ladle, clean and hot jars, clean lids and rings, jar funnel,
bubble freer/plastic knife, headspace measuring device, clean damp paper towel, jar lifter, boiling water
canner with water at 180°F, timer
E. Cooling Station
Jar lifter, clean towel or cake cooling rack

2. Prepare supplies and set up each work station. • If using the canner to heat jars, put on stove
and set heat to medium to medium high.
Add jars making sure each jar is under
water. Do not boil, heat to 180°F.
• If not using the canner to heat jars, fill

water heating. Do not boil, heat to 180°F.
4. Either before class or at the beginning of class
wash jars, lids
and rings.
When Class Starts
• Introductions – teachers and students
Have participants tell if they have ever canned before. If yes, what food?
• Inform students, this will be a guided, hands-on canning experience, encourage them to ask questions
along the way. Let them know when the jars are in the canner, we will be reviewing what we did. If time
permits, use the canning activities included with this lesson series.

Tasks to Start Class
Should I sterilize my jars??
Have students wash hands.
Wash jars, lids and rings, if not done ahead of class. Keep
jars hot by using one of the following methods:
Jars can be immersed into the canner water or other
pot with hot water.
Jars can be held in a clean sink in very hot water.
If the processing time is less than 10 minutes it is
Jars can be run through a dishwasher and held in the

Remove from heat. Skim off foam if necessary.
Tested recipes have specific instructions for cooking - follow them. Your goal is to develop an adequate gel
structure. Best results occur when you use a wide diameter saucepan with a flat, heavy bottom and high sides. The
additional surface space helps with evaporation resulting in improved gelling.
Additional points to remember when cooking jellies:
1. Prepare only a single batch at a time. Doubling the recipe can cause your spread to be soft and not gel.
2. Overcooking or undercooking can affect the set.
3. Pectin recipes have been developed for a specific boil time, always follow the recipe.
4. While cooking your jelly, foam will form on the top. Use a large metal spoon to skim the foam off the spread prior
to filling jars.
5. Use only jar size specified in your tested recipe. It is not safe to use larger jars as this can affect processing
temperature and time.
6. Measure the full amount of sugar listed in the recipe. If you wish to use less sugar, use a recipe specifically
developed to get the taste you want.

7. Using a jar lifter, place the filled jar on the rack in the
canner, being careful not to tip the filled canning jar.
Repeat until all jars are filled or product is all used.

8. If rack is resting on the rim, lower into canner. Water
must cover the jars by 1 to 2 inches. Adjust heat to
medium-high, place lid on canner, and bring water to a

9. Process jars for the amount of time indicated in the
recipe when water is at full boil. Keep the canner
covered for the process time. The heat setting may be
lowered as long as a gentle but complete boil is

Grape Jelly
with powdered pectin
5 cups grape juice (about 3½ pounds Concord grapes and 1 cup water)
1 package powdered pectin
7 cups sugar
Yield: About 8 or 9 half-pint jars
Procedure: Wash and prepare canning jars with two-piece canning lids according to manufacturer's
directions.
During class this step is already done by using commercial grape juice.
To prepare juice. Sort, wash, and remove stems from fully ripe grapes. Crush grapes, add water, cover,
bring to boil on high heat. Reduce heat and simmer for 10 minutes. Extract juice. To prevent formation of
tartrate crystals in the jelly, let juice stand in a cool place overnight, then strain through two thicknesses
of damp cheesecloth to remove crystals that have formed.
To make jelly. Measure juice into a kettle. Add pectin and stir well. Place on high heat and, stirring
constantly, bring quickly to a full rolling boil that cannot be stirred down. Add sugar, continue stirring,
and heat again to a full rolling boil. Boil hard for 1 minute. Remove from heat; skim off foam quickly.
Pour hot jelly immediately into hot, sterile jars, leaving ¼ inch headspace. Wipe rims of jars with a
dampened clean paper towel; adjust two-piece metal canning lids. Process in a Boiling Water Canner or
Steam Canner.
