favourite flavour, vanilla, the key ingredient for sweet treats is now after saffron the second most expensive spice in the world.|j after saffron the second most expensive spice in the world. i have some flavours for us to try. which ones? honeycomb, originalvanilla and rammen raisin. this ice cream business is run by three sisters in cheshire. really creamy. very good texture. the family has been churning ice cream for 13 years but the cost of this creek, key ingredient is starting to bite. the cost of this creek, key ingredient is starting to bitem has gone up, we decided to buy it forward and buy a years worth. we had to make a decision as to whether to absorb the cost, which we did in the end. in the future we just have to sit down, crunch the figures and see how it will work out in the yea rs see how it will work out in the years to come. the sisters insist they will stick with the real thing

but other ice cream businesses are taking vanilla of the menu. so, why has vanilla become such a valuable commodity? here at rhs wisley gardens vanilla orchids are grown inside a special glasshouse, but over 75% of the world's vanilla grows in madagascar. vanilla is currently around $600 a kilo. the main reason for this is there was a cyclone in madagascar last march which damaged a lot of the plantations. despite hopes the prize would have eased by now it is still on the high side around those levels. in fact, on the high side around those levels. infact, it on the high side around those levels. in fact, it means it is higher than the price of cinnamon. highly prized and highly priced ingredient. as a result, only 1% of the flavouring in food comes from actual vanilla plants like these ones. even though you may find it in a sweet scented perfume is, candles, ca kes

a sweet scented perfume is, candles, cakes and 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 fa res. how this year's vanilla harvest fares. the team at snugburys say they will not pass on the cost to customers yet. they say the taste is worth it whatever the price. we are going to return to moscow and the news that vladimir putin has been sworn in as president of russia today, that's 18 years after he was first elected. let's across to our correspondent sarah rainsford there. pretty impressive looking ceremony. he's been speaking. has he had anything interesting to say about how he will use his next few years in power? as you say, an extremely opulent ceremony in the kremlin. interesting that vladimir putin was seen on tv here, live pictures on tv standing

up here, live pictures on tv standing up from his chair in the kremlin putting on his jacket and making his way to that rather glitzy ceremony in one of the kremlin holes with a huge invited audience, of course. what they heard from mr putin after he sworn, had sworn his oath was essentially a pledge to improve life for all russians —— halls. he talked a lot about the economy and russians‘ prosperity going forward and said he pledged he would use this fourth term as president to improve their lives generally. there was little talk specifically about relations with the outside world although there was mention of the need for russia to remain a great country. president putin talked about security and defence being extremely important and said he would continue to pay close attention to those issues, mentioning, though, he was also open

to dialogue, presumably hinting at the relationship with the west, which of course has become extremely complicated in the last year or so. but certainly, the focus was very much on pledging prosperity to the people of russia. they have heard these pledges before. life has got more difficult, the economy has taken a downturn, so the question is how easy it will be for president putin to carry through on those pledges when it gets younger pomp and ceremony of today and the inauguration to the normal business of running the country. sarah rainsford, thank you very much indeed, live in moscow. it is set to bea indeed, live in moscow. it is set to be a record breaker and alina jenkins has the weather. it is likely to be the warmest early may bank holiday on record but there are exceptions to the warmth and sunshine, more cloud in scotland and northern ireland thinking and breaking, some sunny spells save for the far north—west with light and patchy rain. some mist and low cloud on irish sea coasts, always that bit cooler.
