ハマグリ／basket clam

ハマグリはマレー語でケパ（kepah）。マーケットで買うとボール1杯分（1kg）で300円位。

Basket clam is called "kepah" in Malay. We can buy it at Batu Lanchang wet market or Cecil street wet market. The bowl of clams as below is 1 kilogram for RM10.

とっても泥臭いので調理前には泥抜きが必須。開始5時間後。

These clams smell so muddy. Removing mud and sand is necessary before cooking. Five hours passed...

水を換えて、さらに10時間後。
After changing water, ten more hours...

臭いが気になるなら、少なくとも一晩は泥抜きした方が良いと思います。

I think it`s better to remove the muddy smell not for several hours but at least throughout one night if you want to remove it completely.
