I've found something similar !!
It's called a Silicone Universal Tasting Spoon, about 10" long, bright orange (difficult to lose) with a spoon on each end ( one smaller than the other). As it says it was made of silicone and there was only a groove down the centre so not quite what Galen was looking for.There was an email address zeal@cks,uk.net. I found it in Boyes which those of you from these northern outposts (Yorkshire) will know and love and the price was a huge £1.99. Quite a bit cheaper than anything in Lakeland I suspect!!
