Make and freeze the pops: In a medium bowl, whisk together the yogurt, honey, cardamom, and salt. Take a look at your popsicle molds and gauge how thick you need to slice your figs; you want to be able to slide the figs into the molds so they are fairly tightly wedged in place (this will mean you’ll see fig after they’re frozen). Slide 1 large or 2 smaller fig slices into the molds, then press a wooden popsicle stick through the figs down into the bottom of the molds. Pour the yogurt mixture around the figs, moving the figs slightly with your fingers and tapping the molds against the counter to allow the yogurt to fill any gaps and air pockets. Freeze until solid, 3 to 4 hours (or if you have an instant popsicle maker, by all means use that).

Make the magic shell and finish the pops: Once the pops are frozen, combine the tahini and coconut oil until smooth in a glass that can fit the popsicle without it touching its sides. Line a plate with wax paper and place it in the freezer. Loosen the pops by letting them sit out for 5 minutes, or run the outside of the molds carefully under warm water in 15-second increments until they release. Dip each pop in the tahini mixture, pull it out, and let the excess mixture drip off. If desired, dip again; the mixture should harden almost immediately. Place each pop on the wax paper–lined plate as they’re done. Freeze for a few minutes before serving, or wrap each pop in wax paper, then in plastic wrap, and store in  the freezer for up to 1 week.
