Piper retrofractum
Whole long pepper catkins — sweet and resinous at the front, with a heat that arrives late and lingers.
Botanical story · current research
Javanese long pepper is a tropical climbing plant whose compact fruit spikes are harvested and dried as a single aromatic spice. Piper retrofractum is distinct from the Indian species Piper longum: its heat builds slowly, while resinous, woody and gently sweet notes unfold around it. The whole spike carries piperine and aromatic oils that give it more depth and persistence than a simple flash of peppery heat.
Piper retrofractum
Southeast Asia
Known as cabe jawa in Indonesia and dee plee in Thailand, this Southeast Asian long pepper belongs to the region’s own cooking traditions. It is particularly at home in rendang, curries, braises and long-simmered sauces, where the fruit spike has time to release cedar-like warmth and a softly sweet aromatic finish. Green Botanica sources it from a certified organic farm in Thailand’s Isaan region.
Fruit spike · whole dried spice
The dried fruit spike can be infused whole in a broth, curry or braise and removed before serving, much like a bay leaf or cinnamon stick. It can also be broken and ground immediately before use for spice pastes, marinades and finishing blends. Whole spikes keep their aroma longer; grinding changes the preparation and intensity, but both forms remain the same Piper retrofractum fruit.
