When I was young, I dont like to eat sea cucumber, because the shape look very disgusting. But now is my favorite dish especially during CNY, my monther cook a very yummy Pork Knuckle with sea cucumber. Last Year I learned from her on how to prepare this dish, this year I learned from her on how to clean the sea cucumber (Last year my mum clean for me because I'm busy in work, this year no reason not to learn since I had retired from work.
From my mother several trial and error, she has came out with a simple way to clean the sea cucumber.
I would happy to share with you this simple steps rather you go through the hard way to learn it:-
Day 1:-a. In the moning, wash the dried sea cucumber and soak in clean water till night.
b. At night, bring to boil for several minutes, turn off the heat, cover the pot and allow to soak for overnight.
Day 2:-a. In the morning, the sea cucumber has turn soft.
b. Start to clean it, use scissor to cut and wash inside well.
c. Clean sea cucumbers (it took me 2 hours to clean it, not an easy job !!!)
d. Cut few slides of ginger, add into sea cucumber and bring to boil again ( to get rid of the smell). Once done, you can start to use this clean sea cucumber to cook or you may want to pack into container and keep in the frozen area in the fridge for future use.
p/s If you noticed some of the sea cucumber hard to clean, bring to boil and soak it again. And these steps are applicable to small size of sea cucumbers, it may not work well for those big size of sea cucumber.
