Preparing Dry Sea Cucumber

In Chinese, the sea cucumber is called "Hai Sen", "Hoi Sam" or "sea ginseng" is a "yang" or "heaty" food, reputed to be a general tonic and aphrodisiac. Rich in iron and contains minerals like calcium, magnesium and zinc, the sea cucumber has been known to help ease arthritis pain and relief joints discomfort..

Often sold in dried hard form, preparing dried sea cucumber can be time consuming and requires a lot of work. After removing the skin, you have to reconstitute it in water which is drained daily for 4 days, occasionally wash it under running water, boil it with slices or ginger or
pineapple skin in between to remove the “fishy” odor, so that it expands to several times its original size and becomes soft again. Drain and keep in the refrigerator until ready to use. Not prepared properly, it can have a rubbery-tough-to-chew texture that can be unappealing and taste wrong. As for fresh sea cucumber, expanded and sold soaked in water, which can sometimes be found in Chinese markets, needs only a rinse and boil the same way described above. The best kind of fresh sea cucumber is black in color, with smooth surface and fine gloss.

泡发方法

泡发海参时,是烹煮海参最重要,也是最花时间的工序。 干货海参在烹饪须用水泡发,泡发后体积将会变大3至8倍,视乎海参品种及品质而定。
一般厨师用清水加以大块冰块泡发,并存放在摄氏4度的低温下浸泡。在摄氏4度泡海参是为了避免海参在过程中受细菌污染变坏。海参浸泡时必需完全被水浸没,以利完全汲水。以后,每6至12小时更换泡浸的水。以上方法浸泡,一般需时约7至14日。当海参泡浸至半软身时,就可切开海参,清除内脏,然后继续浸泡至完全汲水。
部分现代家庭会采用较先进的真空锅来做泡发处理:先以拍松的生姜块、段放入清水里煮,当水烧至虾眼温水时,关火,放入海参,然后放入真空锅内过夜(约12小时)。生姜的作用是去除海产的鱼腥味。取出海参,换水换生姜块、段,重复以上泡浸工序3至5次,其间同样要清除内脏
泡发时切勿用热水,否则会外表会被煮熟而内里汲不到水,或部分溶化。另外泡发期间切勿沾染油脂等,否则会降低海参吸水膨胀率,可使其变质,甚至会溶化掉。泡发好的海参在长时间高温会溶化,烹煮时应留意海参下锅的时间控制。
泡发好的海参可以马上烹煮,如要存放超过2日才食用,应存放在摄氏-18度以下冷藏,保存期与一般冻肉无异。结冰并不会对海参的质感造成多少的影响,十分方便使用。

挑选干海参有技巧

第一,海参一定要干燥,不干的海参容易变质,而且因为含有大量水分价格实际高出了很多;

第二,购买干海参时一定要挑选干瘪的,现在有不少不法商贩在海参的加工过程中,为了增加海参的重量加入了大量白糖、胶质甚至是明矾,这样加工出来的海参虽然不符合产品质量标准,但因为参体异常饱满,颜色也黑亮美观,对消费者具有很大的蒙蔽性;另外还需要注意的是,有的海参是染色的,在外观看颜色非常漆黑,海参的开口处也是黑色的,里面露出的海参筋都是黑色的,可见利欲熏心的制造者,见利忘义的程度了。
  

第三,购买干海参时不要一味追求价格便宜,要结合干海参的水发率来进行综合比较。一斤好的干海参可以发制出10斤的水发海参,而一斤劣质干参水发后不超过5斤,甚至破碎不堪根本无法食用。
 
海参水发方法(三三三泡参法):将海参置于冷水中,浸泡30小时左右(一海参泡软为止),然后将参剖开,刮掉参内白筋和白皮,洗净后添水上锅加盖煮沸,开锅后用文火煮30分钟左右(视质量掌握时间),待水凉后,换凉水泡三天,每天换一次凉水,春夏秋季一定置于冰箱保鲜层内,保持较低水温,水以不结冰最好,三天后捞出单独冷冻,以后可以随吃随取。(切忌:水发时沾油、碱、酸)。
