The ingredients list is short (open bag of sesame seeds had gone by so I had to open a fresh one). It's not that hard. But that's a fucking lot of equipment to clean up afterwards. Coffee grinder for the seeds. Blender in this case for the final product. And I had to clean the coffee grinder twice, because I hadn't realized the first batch of seeds wasn't good anymore until after I'd ground them. *sigh*
Of course, if I did this more often, it would be less of a chore.
