I only made and tasted this today with plans to use it in a pasta tomorrow night. It was a super simple tapenade to make and the taste was great already. I'm sure a night to stand will only improve it. I didn't have a jar to sterilize, so I piled it into a clean bowl and plan to use it in the next few days. I'm wondering how effective a hot sterilized jar would be once the room temperature mix hit it anyway?
