手把手教你做“外黃內白”的水煮蛋

If you’re bored of hard-boiled eggs having a yellow centre and a white exterior, then you’ll want to pay attention to this wacky recipe for inside out eggs.如果你已經厭煩了裏面黃色外面白色的水煮蛋，那麼你一定想好好看看這個不走尋常路的食譜，教你如何製作蛋黃在外、蛋清在內的雞蛋。

A Japanese chef revealed a method to reverse the colour of your eggs in a YouTube video.
在YouTube的一段視頻中，一位日本大廚揭示了這種調換蛋清蛋黃的方法。

Using a few bits of equipment found around your home - including a pair of tights and a torch - you too can enjoy the novelty of a boiled egg that has its white albumen on the inside, and its yellow yolk on the outside.
用幾樣在家裏就可以找到的工具（包括一雙絲襪和一個手電筒），你就可以擁有這種新奇水煮蛋，白色的蛋清被黃色的蛋黃包裹在裏面。

The science behind it is that the yolk of the egg is more dense than the albumen.
這種現象背後隱藏着科學知識，也就是蛋黃的密度比蛋清的密度大。

When you spin the egg rapidly, the runny yolk is drawn towards the edge of the egg via the centrifugal force, while the albumen is pushed to the centre.
當你快速旋轉雞蛋時，蛋黃收到離心力而流向蛋殼，蛋清則被擠到了中心部位。

If you spin the egg for long enough, the yolk and albumen separate, so that when boiled the egg appears inside out.
如果旋轉雞蛋的時間夠長，蛋黃和蛋清就會分離，這樣再煮，就會得到蛋黃在外、蛋清在內的雞蛋了。

If you don’t spin it for long enough, the two mix so that you get an instant scrambled egg.
如果旋轉的時間不夠長，那麼你做出來的就是即食炒蛋。

What you'll need: An egg, clear tape, a torch, a pair of tights and ice cubes.
你需要：一隻雞蛋，透明膠帶，一個手電筒，一雙絲襪和一些冰塊。

1. Check the colour of your egg with a torch.
用手電筒照一照，看看雞蛋的顏色。

2. Put tape around the whole shell of the egg.
用透明膠帶把整個蛋殼纏一圈。

3. Wrap it in the middle of a pair of tights.
把纏好膠帶的雞蛋塞進絲襪裏。

4. Spin it round for a few minutes by holding either end of the tights.
抓住絲襪兩端，旋轉幾分鐘。

5. Check on the colour again. It should be darker than in step one.
再檢查一下雞蛋的顏色，應該比第一次看時顏色深。

6. Take the egg out of the tights and place it in boiling water with the tape still on.
把雞蛋從絲襪中拿出來，不要拆掉膠帶，直接放到開水中煮。

7. Once boiled, remove the egg and place it in a bowl of ice for a minute.
煮沸後，把雞蛋拿出來，放到裝有冰塊的碗中冷卻一分鐘。

8. Now peel the shell, and you should now have an inside out egg. If the whole thing is yellow, try it again but spin it for longer.
剝掉蛋殼，你就做好了一個蛋黃在外、蛋清在內的水煮蛋了。如果整個蛋都是黃的，那麼下次做的時候載旋轉久一點。
