Ataulfo mangoes are only available in the Toronto area from late March until September. I don't know what the availability is in other regions. They are 8 to 10 inches long with an oblong round-bottom shape and a gold-blushed yellow skin. The juicy flesh inside is yellowy-orange, creamy smooth, free of fibrous stringiness (which can set off allergies in people sensitive to stone fruits) and is described as the best thing to have fallen out of a tree since the apple observed by Isaac Newton. The flavour resembles a delectable combination of peach, banana,m pineapple and butter. They're incredibly sweet and loaded with vitamin c and dietary fibre. Look for them in your local Chinatown.
