Hi Cactus, I know exactly what you mean. I have a joke that roasted cashew butter smells like 'pet'. Think of this the next time you smell it- it's pretty funny. Raw cashew butter works better as a base for vegan ice creams than anything else I've been able to find. The problem is that it's so hard to find and roasted cashew butter doesn't really work. This is why all of my new ice cream recipes are based on raw cashews which are easy to find.
Thanks for stressing the issues you had with roasted cashew butter and bringing this to everyone's attention! I've updated the recipe to stress using raw cashew butter and to not use roasted cashew butter. I may rework this recipe with Jackie in the future for raw cashews and save everyone the hassle of looking for raw cashew butter.
