Toby called me to say that he needed my services with a rather bizarre request. He worked for a catering company and needed me to detect trays and trays of macadamia nut caramel tarts. I was a little amused, but it was all to make sense soon enough. The company had recently purchased a new mixer for mixing large containers of caramel for their desserts. The mixing blades had somehow come in contact with the edge of the aluminium container making indentations in the sides (possibly shearing off little pieces of metal actually in to the caramel).
Toby needed my help in establishing if small pieces of metal had indeed been put in to the mixture which were now in ready-to-serve tarts. There was a room full of these delicious looking (and smelling) desserts. The pieces of metal would be very small so I used my most sensitive machine, my Fisher F75 as I knew this was the only chance of finding them. I asked him to carefully put some baking paper over the top of the tarts so I could get the head of the detector as close as possible to the caramel greatly increasing my chances.
Sure enough the second tray of caramel tarts gave an ominous signal. We cut out the target area and sure enough inside the caramel was the smallest shard of aluminium. I continued detecting different trays of tarts, constantly finding more pieces of the troublesome metal. Toby was disappointed, but was so thankful I had found the metal so he could throw the desserts away so no customers got a nasty surprise in their mouth in a few days time. It could have ruined his business. Another happy(ish) customer!
