you may tempted to indulge in an ice cream or two. but, if your favourite flavour is vanilla, the price you pay for it could be about to rise. bad weather in madagascar, the world's top producer, has affected the harvest and is pushing up prices. our business reporter maryam moshiri has been to see how businesses are coping. cookie dough, chocolate brownie, creme brulee, whatever your favourite flavour, vanilla, the key ingredient for sweet treats is now, after saffron, the second most expensive spice in the world. i have got some flavours for us to try.

i've got honeycomb and original vanilla and rum and raisin. snugburys ice cream is run by three sisters in cheshire. the family's been churning ice cream for 30 years, but the cost of this key ingredient is starting to bite. yes, it has gone up. we decided to buy it forward and buy a year's worth. we had to make a decision as to whether we were going to absorb the costs, which we did in the end. this summer, we have to crunch the figures and just see how it will work out for the years to come. the sisters insist they'll stick with the real thing, but other ice cream businesses are taking vanilla off the menu. so why has vanilla become such

a valuable commodity? here at these rhs gardens, vanilla orchids are grown in this glasshouse, but 75% grows in madagascar. vanilla is currently around $600 a kilo. the main reason for this is that there was a cyclone in madagascar last march which damaged a lot of the plantations, and despite hopes that the price would have eased by now it's still on the high side, around those levels, and, in fact, this means that it's higher than the price of silver. a highly prized and highly priced ingredient. as a result, only 1% of the flavouring in food comes from actual vanilla plants like these ones. and even though you might find it in sweet scented perfumes or candles, cakes, or even cocktails, do beware, because cheaper alternatives can be extracted from wood and even petrol. it will take untiljune to find out how this year's vanilla harvest fares. the team at snugburys say they aren't passing on the cost
