This is mom's chilli padi tree in her garden. Neighbours and relatives are all welcome to pick them. They are very spicy and can be eaten raw, perserved in vinegar or used in curry or sambal dishes.
Chilli padi (padi is the Malay word for paddy refering to the rice grain it resembles) or cabai burung is also known as bird's eye chilli. The birds love to pick the ripe ones which are bright red. We pick the green ones so they preserve better. The tree is about a meter high and you only need one tree for the whole neighbourhood. The flowers are white and the fruit is only about 1 inch in length.
The ones sold in Singapore is a different variety and they are about 2 inches in length and not as spicy as these ones.
