Wood apple

There wouldn't be a discussion of Sri Lankan food without wood apples.

Wood apple is a Southeast Asian fruit about the size of a dehulled coconut. It also has an equally hard shell and has an aroma like blue cheese.

Strolling through a market in Sri Lanka, your nose will spot it long before your eyes will. Inside the rind was a dark brown paste resembling something between tamarind pulp and fermented raisins.

Wood apples can be eaten straight from the peel, but one of the most popular ways to eat (or drink) it throughout Sri Lanka is in a thick smoothie known as apple juice.

The fruit is mixed with jaggery (or sugar) and water until smooth. It has a unique sour and sweet taste. Mention that you love the wooden apple to any Sri Lankan you meet, and they probably won't be able to hold back a knowing smile.
