Hi. I have some tahini in the cupboard from about 6 months ago. When I used it last night it had this really spicy kick to it. I was surprised since it didn't taste like that last time I used it. So I started wondering if it had gone bad. I always thought tahini was like peanut butter in that it stays in the cupboard indefinitely. Am I wrong? Was I supposed to refrigerate it? I doesn't say much on the label except that it contain no additives or preservatives... I'm wondering if that's why it didn't last..
Any insight would be appreciated.
