Lemon Juice

Processing: Boiling Water Canner 10 minutes
Storage: 12 months +
Extract the juice from your homegrown (or locally sourced) lemons, to enjoy all year long! Also suitable for preserving if you check the pH before bottling.

Juice lemons.

Juice lemons, discarding peels, pulp and seeds. Strain juice through a sieve, jelly-cloth or cheesecloth. Refrigerate juice overnight.
Prepare jars.
Prepare jars (we prefer using glass bottles) by covering in water and boiling for 10 minutes. Then turn the heat off, keep pot covered and leave jars hot until ready to fill.
Heat juice.
Strain juice into pots, leaving sediment and any pulp behind. Test pH using an electronic meter (or pH strips) if you will be using your lemon juice for preserving in the future (your homemade bottled lemon juice needs to be the same acidity as commercial bottled lemon juice). Bottled lemon juice has an acidity of 4.5% or more (pH needs to be 3.8-4 or less). Heat juice over medium heat for 5 minutes (do not boil).
Prepare lids.
Warm lids in a bowl of boiled water. Let the lids heat through for a few minutes while you fill the jars, removing the lids from the water when you are ready to place them onto the jars to seal.    
Ladle hot juice into hot jars.
Immediately ladle hot juice into hot jars, leaving a 1/4 inch (0.5cm) headspace (distance between the juice level and the jar rim). Wipe jar rims with damp paper towel then seal with the warm lids.
Boiling water bath processing.
Process in boiling water canner for 10 minutes (or as stated in the chart below for your altitude). Start timing when the water returns to a full boil. Once the time is up, turn the heat off and rest jars in the water for 5 minutes before placing onto a towel-covered bench overnight to cool.
