One man feeling the effects is Steven Darvill, owner of The Handmade Ice Cream Company at Lakeside, who says poor crops on the African island have seen prices soar.
"I spoke to my supplier and was told there's a six to nine month drying time for vanilla and it was a poor crop last year, and the year before that wasn't particularly good either," he said. "Prices have been dramatically put up.
"It has had a massive impact. We don't use any artificial vanilla we only use pod. It's what we set out to do, it's the whole handmade ice cream ethos so we will have to absorb the costs. We will just take the hit and hope for a better crop next year."
