This recipe is one of my first experiments making a vegan "cheese" style sauce. It is from "How it all Vegan", which is such a fabulous book. When I first made it, I misread and used sunflower seeds instead of sesame - and now I'm not sure which version I like better. If you're wondering, the consistency is similar to hummus, and if you've never made one of these so-called "cheeses" don't expect it to be like the dairy cheese you know, it's quite different. Great, different. Note that this makes quite a bit - the recipe says 1 cup, but I'd say it's close to 2. So if you're using this as a sandwich spread, that's quite a bit to go through unless you try freezing (I haven't tried that yet). According to the book it should last 7-10 days. Having said that, if you've got people over - put this out with some crackers and it won't last long!
