I have a "best friend" baker friend who makes the most excellent cakes and she made the cake for my parents' 60th anniversary. Two-tiered white cake with pineapple filling and beautifully and elegantly decorated. There was a silver foil round bottom underneath, wooden dowels throughout. During the celebration we ate the top tier. a few days later we cut into the bottom tier and YUCK! it tasted like bug spray or chemicals or gasoline. It was delivered by my friend and never moved from the spot we served it. It didn't come in contact with any chemicals before or after delivery that we are aware of. It looks so beautiful and you can smell the chemical smell somewhat, but the taste....horrific...like it actually made the tip of my tongue feel numb/tingly. What could have caused this? The whole bottom tier of the cake is wasted now.
