Can heat affect the taste of fondant?

Been making cakes for quite a while without a single complaint. Last week made a cake using DH cake mix, buttercream icing (Wilton crisco-only recipe), and Satin Ice fondant. The cake tasted great as usual, I tasted the buttercream (normal), and I always use Satin Ice because it's always great. Customer came in saying the fondant tasted "mediciny". I came home and tasted the fondant. It was the normal yummy flavor. I used the blue and red precolored. They tasted just fine.

Could it be because she put the cake in her trunk for an hour driving home on a hot day? She's used to my fondant covered cakes so she knows what fondant tastes like...

Any clue anyone?

TIA

If she put the cake in the hot trunk for an hour drive, its a wonder she had a cake left to serve. But yes i would say that could do the trick.

Maybe due to the heat in her trunk it picked up a taste from things that have been in the trunk previously.

Well, it is possible for the exhaust from her car to come into the trunk, soooooo she might have just been eating a carbon monoxide cake!

It can also depend on what she was eating/drinking right before she tasted the cake. Lots of folks don't realize one flavor can affect another.

I'm thinking it picked up the odors from the trunk......
