Peaches are one of the only fruits that also smell delicious. Most other fruits either don't have much of a smell or it's fairly subtle. Guavas are a definite exception to that rule - usually if you like like the smell of them, you also like the taste of them. I like neither. Then there's the South East Asian fruit, the Durian. I've never smelled or tasted them, but it's usually said to have an obnoxious, overpoweringly putrid odor. It's related to the Indian jackfruit, which I've tasted but not smelled - I usually arrive in India only at the tail end of their season.
