Here's what Pelagonia - the food company based in Macedonia - say about their Wild Green Fig Jam:

"During the spring time we see young hard figs form on the trees here in Macedonia and harvest them for our jam. Most fig jams are made with soft ripe large figs, but ours is made with the young green figs - plus a twist of lemon - and has a unique flavour and fragrance. The figs are boiled several times before making the jam."
