pounds fresh ripe figs, stemmed and chopped (about 6 cups)
large sprigs fresh rosemary (wrapped and tied in cheesecloth)
cups granulated sugar
tablespoons lemon zest (from about 4 lemons)
cup lemon juice (from 1 to 2 lemons), plus more to taste
teaspoon kosher salt (Diamond Crystal), plus more to taste
- Place the figs in a 4-quart heavy-bottomed pot. Pour in 1 1/2 cups water and bring to a simmer over medium heat. Cook uncovered, stirring occasionally, until the figs soften and the liquid begins to thicken, about 10 minutes.
- Add the rosemary and sugar, and stir until the sugar dissolves. Bring the mixture to a simmer over medium-high heat. Cook, stirring frequently, until the syrup thickens, the figs are mostly broken down and the jam goes from a rapid boil to slow bubbles, about 25 minutes. Remove and discard the rosemary.
- Stir in the lemon zest and juice and kosher salt. Reduce the heat to medium-low and cook for another minute for a runnier jam or up to 8 minutes if you prefer a thicker jam. Taste and adjust with more lemon juice and salt as needed. (Adding lemon juice will thin the jam, but it does thicken as it cools.) The jam should be sweet and tart with a hint of fresh rosemary.
- Transfer to sterilized jars and can, or cool to room temperature, then store in the refrigerator for up to 4 weeks.
