I made this a couple of weeks ago but have just gotten around to writing up the post. As usual I used Pomona pectin which is very forgiving with the amounts made. You can increase or decrease the recipe with no problems.
I picked figs with no particular amount in mind. I ended up with 6 cups once they were all mashed. I added in 6 tablespoons of lemon juice and 6 teaspoons of Pomona calcium water. In a separate bowl I added 4 ½ teaspoons of Pomona pectin and 1 ½ cups sugar. I love using less sugar as it really makes the flavor of the fruit the star of the jam.
Once the fruit mixture came to a boil, I dumped in the sugar mixture. Once it came back to a good boil, I filled half pint jars. (Jams/Jellies which are low in sugar do not last as long as those full of sugar.) I processed these in a water bath.
