Figs are a delicious and nutritious fruit and there are several ways you can preserve them. To make a jam out of figs you would chop up three to four cups of figs and place them in a medium-sized pot with enough water to cover the figs. Furthermore, add five cups of sugar and three teaspoons each of lemon juice and vanilla. Let the figs cook down for 15 to 20 minutes then place in canning jars and put lids on the jars. Another way is to boil the figs for thirty minutes and then place them in jars along with lemon slices. Fill the jars with water and place the lids on the jars before putting the jars in hot water for a few minutes. Finally, remove the jars.
