Spoon yogurt into a fine mesh sieve and let the whey drain overnight or for a couple of hours to make hung curd. I didn't plan ahead, so I ended up draining mine for only a half hour. This made no difference to the taste.
Pre-heat oven to 200 degree celsius.
Arrange figs on a roasting pan and drizzle with 2 tablespoons honey. If using slit the vanilla bean, scrape out the seeds and toss seeds with figs.
Place in the oven and roast for 20 minutes.
Mix cardamom powder in the yogurt and let it stand for ten minutes.
To serve, place 2-3 figs in each bowl, spoon yogurt on top and drizzle with remaining honey and fig juices collected in the pan.
