上個post提過隻龍蝦係雪櫃拎出黎已經長眠左，所以煮完出黎d肉質唔夠結實。買得龍蝦當然想佢煮個一刻都係最新鮮，所以之後我地上網搵多左少少龍蝦保鮮既資料，發現各適其式，以下歸納幾種見過既方法:

1) 買到返屋企由龍蝦尾部捅入筷子貫穿蝦身放尿，然後放入雪櫃
2) 用鹽水養住龍蝦直至煮既時候
3) 就咁放入雪櫃直至煮

究竟咩去做龍蝦保鮮方法先岩?今次同你分享下我地既龍蝦保鮮資料搜集結果。文章既下半部份都會同大家分享劏龍蝦同開邊龍蝦兩個龍蝦處理方法。

In our last post we mentioned that the lobster had already passed away when we took them our from fridge so the texture was not as perfect as a living one. We don’t usually cook lobster but when we do, we want it the most fresh. Hence we looked into ways to keep a lobster fresh on the internet and we discovered that there are actually various ways of doing that. The below were some of the approached we came across:

1) Stab a chopstick through the lobster tail from the anus for releasing its “urine” and then put it into fridge
2) Keep the lobster alive in a pot of salted water until we cook it
3) Simply put it into fridge until cook So which method is right? Let’s continue reading.

龍蝦保鮮法 Ways to Keep a Lobster Fresh

3種龍蝦保鮮方法既短評:
1) 放尿再放入雪櫃
首先龍蝦既尿係由觸鬚旁既排泄孔排出，尾部既窿其實係肛門，由肛門捅入去既係龍蝦腸，入面可能有糞便，但龍蝦腸黎講，根本你拆開龍蝦既時候就咁拎出就得。而流出既透明液體係龍蝦血，新鮮龍蝦血無異味的，煮熟會變成蛋白狀。最近美國更更有大學教授話研究緊用龍蝦血對抗武漢肺炎… https://bit.ly/3f3KkYa

再者，放尿依個動作睇上去都幾殘忍，我唔知龍蝦有無感覺，但好似會令佢更痛苦咁。同埋放左尿無耐佢就會死，做唔到龍蝦保鮮。

2) 用鹽水養住龍蝦
葉師傅，唔係咁易架。要用水養住龍蝦保鮮，鹽度要保持28-35ppt，仲有溫度、含氧量、含氨量同酸鹼度都有講究。唔係要同隻龍蝦過人世既話都係捨難取易好d!

3) 就咁將龍蝦放雪櫃直至煮
我今次就係咁做，不過隻龍蝦都瓜左。其實應該要用濕毛巾包住龍蝦放入冰格，保持濕度之餘令佢既生陳代謝減至最低，所需既氧份自然少d同可以活耐d。似乎依個係最簡單直接既方法。

Brief comments on the aforementioned ways to keep a lobster fresh:

1) Releasing “urine” and put it into fridge
First of all, the urine of a lobster is released from the excretory pores on the antennae and there is nothing to do with the anus. When we are actually stabbing through the intestine of the lobster with the chopstick. Inside the intestine there may be faeces but actually we will take out the intestine anyway before we cook. The transparent liquid pouring out when we stab the lobster is actually its blood which has no unpleasant odour. When it’s cooked it condenses like egg white. In the US there is also recently a research suggesting that lobster blood is potentially a cure for COVID 19…

In addition, the action of chopstick stabbing actually looks inhumane. Not sure if a lobster has feeling or not but it makes the lobster struggles. Also soon after being stabbed the lobster will die so it cannot be kept fresh anyway

2) Keep it fresh with salted water
That’s in no way an easy task. To keep the lobster alive, salinity will need to be within 28-35ppt . Also the temperature, oxygen level, nitrogen level and pH value are all need to be in control. If you’re not going to keep the lobster for a long long time, you better forget this method

3) Simply put it into fridge
That’s what we did this time but the lobster still died before cooking. Actually we should use wet towel to wrap the lobster and put it into the freezer to minimize its metabolic rate. The oxygen required by the lobster will hence decreases to lowest level and it can then be kept for longer. Looks like this is the simplest working way.

係肛門插入筷子點聽都唔係個好主意…
It doesn’t sound like a good idea to stab a chopstick in the anus…

龍蝦處理－劏龍蝦 Cut Open A Lobster

講完龍蝦保鮮，簡單講埋點拆龍蝦。先沖沖水
After talking about how to keep it fresh, let’s talk about how to actually prepare the lobster. First we briefly rinse it

捉住蝦頭蝦身，360度扭開佢
Grasp the head and tail, twist it in circle

咁就分離出兩部份
We can then separate that into two parts

修剪觸鬚
Trim the antennae

將頭分開上下兩部份
Separate the head into 2 parts

搣走腮
Take away the gills

剪走龍蝦腳
Remove the legs

將龍蝦身劈開一半
Chop the tail into 2 pieces

搣走龍蝦腸，完成！斬埋件就可以煮上湯龍蝦伊麵喇！
Take away the intestine. Done! We can proceed to cooking the lobster noodles!

龍蝦處理－開邊龍蝦 Butterfly A Lobster

另一餐我地就係買左兩隻澳洲龍蝦返黎，即刻就焗，可以睇睇我地芝士焗龍蝦既食譜。
買左龍蝦返黎，驚佢四圍郁既話，放入冰格15分鐘令佢暈低先，然後快狠準咁如圖將刀尖捅入頭部末端位置，一刀令佢唔再有機會掙扎

In another meal we bought 2 Australian lobsters for baking once after we arrived home with them. You may refer to our Cheesy Baked Lobster recipe.
The best way to get rid of a hyperactive lobster is to put it into freezer for 15mins. Then stab a pointed knife into the lower end of its head quickly and accurately. This is enough to stop it from having further motion.
