No, it's not a funky artichoke—this heart-shaped fruit native to South America is a cherimoya, also referred to as a "custard apple." While it may be rough and bumpy on the outside, the actual fruit flesh is smooth and creamy, like custard. Described by Mark Twain as “deliciousness itself,” a ripe cherimoya blends flavours of pineapple and banana. Can’t find it in your grocery store? Bottled water brand Aquafina now makes a Tropical Cherimoya flavoured water.
