While the base is cooling. Combine the figs, water, honey, sugar, lemon juice, cinnamon, cardamom, and salt in a medium saucepan. Bring the mixture to a simmer. Cover the pan, adjust the heat to maintain a simmer and cook for about 5 minutes. Uncover and continue simmering, stirring frequently at first and constantly at the end, until the liquid is completely reduced and the mixture resembles thick, sticky, chunky jam. Scrape into a bowl. Let cool and then refrigerate until needed.
