Rach Goc crab has had a brand name from the ancient time because the crabs in this locality are actually more delicious than those of other places. The seventh and eighth months of every lunar celendar are the crab season. This crab eats the fallen fruits of avicennia germinans, so it has ochre crab-roe and its meat tastes scented and is firmer than other places. The crabs after being caught are washed and salted on the spot. After salt penetrates the crabs for 5 to 7 days, they can be edible.
Besides, the crabs are processed by boiling with citronella and are eaten with a sauce. The sauce which is processed simply but very special includes chopped citronella mixed with nematode rice, a little capsicum for pungent flavour and a little spice. With this eating way, the crabs taste sweet and scented since the mixture of tear gas from the capsicums, citronella and sour taste and strong gas from nematode rice. Boiled crabs which are eaten with sauce are integral dish for tourists.
