Yellow Dragon Fruit - The official name of this least-known species is Pitahaya amarilla. They are cultivated in Keningau in small amount. They are sold out fast before others know about such fruit. The sellers told me that the peak fruiting season of Yellow Dragon Fruit is between Oct and Dec. Yellow Dragon Fruit is also sold in other months, but in very limit quantity.
Yellow Dragon Fruit is the smallest among the 3, but the sweetest and most expensive, which is RM20 (≈USD6.70) per KG. You can find Yellow Dragon Fruit at fruit & vegetables shops of Foh Sang and Bornion in Kota Kinabalu, but it’s not always available.
However, the taste of Yellow Dragon Fruit is the BEST! Its sweetness is double of Red-fleshed Dragon Fruit, and it has no sour taste.
