Two white peaches and the cross-section of a third. Peaches (Prunus persica) can have either white or yellow flesh. Peaches with white flesh typically are very sweet with little acidity and are the most popular kinds in East and Southeast Asian countries. Meanwhile, Europeans and North Americans have historically favoured the yellow-fleshed kinds, which typically have an acidic tang coupled with sweetness, though this also varies greatly.Photo: Fir0002
