Batag-Batag Kabalang is the Bicolano name for the fruit that the Tagalogs call susung kalabaw (carabao’s teats).
Scientific name: Uvaria rufa (Anonaceae)
It is a wild, annual Southeast Asian fruit available usually from August to December. In the Philippine, the tree grows mostly on the island of Luzon. Even there, it’s not such a widely recognized fruit.
The outer skin is red, and the white flesh is fleshy and pulpy like that of a mangosteen. It has many dark seeds.
There are similar-looking related species like the Cyathostemma viridiflorum with different skin color, ranging from yellow to greenish-gray.
What does it taste like? It’s sour and sweet like an orange or lemon.
The smell is like that of a lychee.
