I have used strawberry, grape and peach jello and are all very good. The juice from the mashed figs is your liquid. You may have to adjust your times on cooking as I did and put my times in the directions. And I also have tried with real strawberries and made it chunky but I prefer the smooth. Give it a try and let me know how it turns out.
Prepare your jars...wash figs and cut off stems. Mash with potato masher or put in food processor is what I did.
Put figs in cooking pot,and add 3 cups of sugar and 1 box of large jello of your choice (strawberry). Stir and cook on medium heat until boiling,constantly stirring.A foam will form but will dissipate.
Takes about 15-20 min..will turn a deep shade of red and will coat the spoon. As quickly as you can fill your jars and screw down tightly. Immerse jars into boiling water bath making sure the jars are covered,boil for 10-15 min.
Remove from water and let cool. Approximately 4-6 small jelly jars (8oz jars)
