Prepare a water bath canner, jars, lids and rings before beginning. The canner should be pre-heated for hot pack to a gentle simmer, about 180 degrees F.
Bring a pot of water to a boil on the stove and blanch the figs for 2 minutes. Drain and discard the blanching water.
Add measured water and sugar to a stock pot and bring it to a boil. The measurements in this recipe make light syrup. See notes for other syrup types.
Add blanched figs to the boiling syrup and boil for 5 minutes.
While the figs are boiling in syrup, add lemon juice or citric acid directly to the empty canning jars. You'll need to add 2 Tbsp. of bottled lemon juice per quart, or 1 tbsp per pint. If you're using citric acid, you can use 1/2 tsp citric acid per quart or 1/4 tsp per pint.
Use a slotted spoon to fill the canning jars with figs, and then ladle the canning syrup on top. Be sure to leave 1/2 inch headspace.
Seal the jars with 2 part canning lids and process them in a water bath canner for 45 minutes for pints and 50 minutes for quarts (below 1000 feet in elevation). See notes for processing times for higher elevations.
Once the processing time is complete, turn off the heat and allow the jars to sit in the canner for an additional 5-10 minutes. This partially cools the jars and helps prevent siphoning as the jars are removed from the canner. Use a jar lifter to remove the jars to cool on a towel on the counter.
Check seals after 12-24 hours. Store any unsealed jars in the refrigerator for immediate use. Properly canned and sealed jars will keep on the pantry shelf for 12-18 months.
