Get ready to pay more for a scoop of vanilla ice cream this summer.

A shortage in the vanilla crop by two of the world's major suppliers is prompting nervous buyers to stockpile the key ingredient of vanilla ice cream and drive up prices, The Telegraph reports.

Mexico's output is expected to fall a whopping 90%, according to the British consumer goods magazine The Grocer, while India is reportedly having problems with the quality of its crops.

The global price -- which has remained steady for at least six years -- has already jumped from $25 per kilo to between $35 and $40, according to The Telegraph.

If manufacturers start passing along price hikes to consumers, it could drive up the cost of ice cream -- as well as medicine and perfumes -- by as much as 10%.

So all eyes are now on Madagascar, the world's largest producer.

Nick Peksa, director of the market analysis firm Mintec, tells The Grocer that in 2003 the price of vanilla soared to $550 per kilo after a hurricane hit the island.
