Fancy an ice cream bean for dessert?

Wolfgang Stuppy
12 July 2013

For the IncrEdibles festival Kew's resident seed specialist Wolfgang Stuppy is contributing bite-size features about weird and wonderful edible plants from around the world. In the second of the series - the incredible ice cream bean!

When travelling to far-away tropical countries, we are likely to encounter strange-looking but excitingly delicious fruits. One of these scrumptious exotics is the South American ice cream bean (members of the genus Inga spp, Leguminosae, for example Inga edulis, Inga feuilleei and Inga rhynchocalyx).

  • Guaba The ice cream bean is locally known as ‘guaba’ (pronounced ‘wuba’). Behind this mouth-watering name lies a beautiful tree with a remarkable fruit.

  • Height An ice cream bean tree produces bean-like pods that can exceed two metres in length and grow 30m (96ft) off the ground.
  • Sweet seeds Inside, lined up in one row, the pods contain numerous large purple-black seeds embedded in an edible, translucent-white pulp. The sweet flavour of the spongy pulp resembles that of vanilla ice cream, hence the name.

  • Spectacular flowers It’s not only the fruits that make Inga trees so very special. Their flowers, which produce the delicious ice cream beans, are pretty amazing too. They only open for one night and wither very quickly in the early morning. Like many other nocturnal flowers, they are large, white in colour and arranged in dense clusters (inflorescences).
