Dabai ( Canarium
odontophyllum ) is an exotic fruit indigenous to Sarawak. It is normally consumed as vegetable, occasionally
made into cakes.
Dabai is a seasonal fruit, available at the same
time as the durians. It is pre-soaked in warm water to softened it
before consuming with some soy sauce and sugar. It’s a bit creamy, some describe it as similar
to avocados. An acquired taste, I may
put it, not everyone would enjoy it.
Yet, it is still a well received fruit-vegetable
among Sarawakians.
However, dabai is a highly perishable produce. It cannot be stored for long after harvest. Once soaked, it must be consumed
immediately. So, it is very hard to acquire during
off-seasons.
One day, in Miri’s Aunt Hong new house, I learned
that there is a folklore technique to store the dabai fruits. The fruits
are kept in the freezer, without being pre-washed. When required, wash and put the dabai in room
temperature to defrost. Once its
defrosted, just add in soy sauce and sugar to marinate. Soaking in warm water not required, as the freezing
will damage the plant cell membranes, resulting of the dabai fruits to
softened.
Apparently, the freezing burst the plant cells as moisture
will slightly expand when reaches temperature of approximately 4°C. When water almost reaches the freezing point,
it expand by approximately 9%. Damages on cell wall means softening of
tissue.
However, the freezing method requires more proper
study.
