Malaysian fruit, desert and reeceipes?

hello, i am originally from Malaysia but am living in the UK. I have recently began to have cravings for Malaysian food, especially the fruit and desert. I love Durian and Rambutan and also the desert called Ice Kachan (i may have spelt it wrong) i was wondering if anyone could either give me recipes and also tell me where i can buy Malaysian fruit in London. Any help would be grateful. many thanks
