Wash, hull, and crush strawberries one layer at a time with a potato masher, in a pot or enameled Dutch Oven. If it is too hard to crush the strawberries pulse them in a food processor.
Bring to a boil. Cover and reduce the heat. Simmer for 5 minutes.
Pour the Strawberries through a mesh strainer lined with 3 layers of dampened cheesecloth into a bowl. Let strawberries drain for 2 to 4 hours or until the juice measures 3 cups. To avoid cloudy jelly, do not press or squeeze the strawberries.
Alternate Juicing Method. Using a steam juicer is an alternate method to get the strawberry juice required for this recipe. Add water to the bottom section of the steam juicer. Add the middle and top sections of the steam juicer. Add your strawberries to the top section of the steam juicer and add the lid. Turn the steam juicer to medium-high heat until the water begins to boil. Juice your strawberries until you have at least 3 cups of strawberry juice.
Wash your jars and lids in warm soapy water. Make sure there are no chips or bubbles in your jars.
Prepare your cannerUsing Water Bath Canner:Put your water bath canner on your stove. Add your canning rack to the water bath canner. Add enough water to cover jars with at least 2-3 inches of water. Start to bring your water to a boil. Using a Steam Canner:Put your steam canner on your stove. Add the steam canner rack to the bottom of the steam canner. Add the recommended amount of water to the steam canner according to the manufacturer. Put the lid on your steam canner and start your stove.
Combine the strawberry juice and the pectin in a stainless steel pot or enameled Dutch oven. Bring mixture to a rolling boil that cannot be stirred down, over high heat, stirring constantly.
Add the sugar, stirring the mixture to dissolve. Return the mixture to a full rolling boil. Boil hard for 1 minute, stirring constantly.
Remove from heat. Skim the foam off top of jelly, if necessary.
Once you have hot jars and hot jelly.Water Bath Canner:Remove your jars from the boiling water one at a time using your jar lifter. Dump the water out of the jar into your water bath canner to ensure there is still 2-3 inches of water above your jars.Steam Canner:Remove the steam canner lid and remove your jars one at a time using your jar lifter.
Ladle hot jelly into hot jars, leaving 1/4 inch (.5 cm) headspace (Check with headspace measurer). Remove air bubbles with a de-bubbler and adjust the headspace by adding more hot jelly if necessary.
Wipe the rim to ensure a good seal is made with the lid. Center the lid on the jar and screw the band down to fingertip tight. Repeat until all jelly is used.
Place jars in the canner with your jar lifter.
Water Bath Canner:Lower the water bath canner rack into the boiling water. Ensure your jars are covered by at least 2 inches of water.If your water is not boiling start your processing time when the water is boiling. Process 1/2 pint jars for 10 minutes. Make sure to adjust your time for altitude.Set a timer, it makes it much easier to make sure you process for the correct time. When your timer goes off turn off the heat and remove the canner lid.Leave the jars in the water for 5 minutes.Steam Canner:Put the lid on the steam canner. Turn your stove on high until your steam canner water comes to a vigorous boil. Continue heating so the indicator is in the correct "Zone" per your altitude. Start your processing time when the needle reaches the maximum point you have tested your steam canner to reach in your "Zone".Adjust the burner so that it maintains an even rolling boil throughout the entire processing time. Usually, this will be much lower than where it was set for the vigorous boil. If the top lid is lifting and/or spitting water from the edges this is an indication that you have the heat turned up too high. Slowly reduce the heat until this stops. Watch the indicator to ensure the temperature does not decrease.The processing times for steam canning are the same as for water bath canning. Process 1/2 pint jars for 10 minutes.Make sure to adjust your time for altitude. Set a timer, it makes it much easier to make sure you process for the correct time.When your timer goes off turn off the heat and let the canner stand for 5 minutes with the lid on before removing the jars. The lid MUST remain ON the canner during this time. This cool-down period is necessary to ensure the jar contents are properly processed.Carefully remove the lid by tilting it away from you to avoid steam burns.
Using your jar lifer carefully move the jars onto a wire rack or kitchen towel to allow them to cool. When moving the jars try not to tilt them to the side as this could affect the seal of the jars. Allow your jars to cool for 12-24 hours before handling.
Once cool, remove the canning rings from the jars. Wash your jars off to ensure no food residue on the outside of the jar from processing. Label your jar with the name of the recipe and date. This will help you remember what recipe you used to can and the date will allow you to use the oldest canned goods first.
