Tahini-Lemon Savory Frozen Yogurt

Just made this stuff through pure improv, and it came out awesome. It's going to be served with falafel and harissa as a sort of mutant sundae.

Tahini-Lemon Frozen Yoghurt

Mix together:
3 C Whole-Milk Yoghurt
2/3 C Tahini
1/2 tsp salt
1/2 tsp white pepper
Juice of 2 lemons (meant to add the zest, too, but the juicing device turned 'em inside out, the flavor's bright without it)
3 Tbs sugar
2 Tbs vodka (helps keep ice crystal size small -- I used Stoli Mandarin, but a lemon-flavored would be even better)
1/4 C sesame seeds

Process in your ice cream maker as usual.

Throw some pistachios in and you've got a frozen halwa. Or something. Sounds awesome BTW.
