When you boil a chicken ’s testis , the semitransparent albumin turns white as it coagulates , create the snowy - with - a - yellow - center boiled testicle many of us are familiar with . Do the same to a penguin egg , and you end up with a very dissimilar aesthetic . rather of turning white , the albumen stays semitransparent , create a very peculiar - await testis in which you’re able to see right through to the yolk .
Can you eat a penguin egg?
“ There are about 17 species of penguin and the egg of several have been used for nutrient on many occasions , ” sound out Robert Headland , fourth-year associate of the Scott Polar Research Institute at the University of Cambridge , UK , to IFLScience .
While in late year it ’s become illegal to hunt penguins or their eggs in some parts of the populace , during Antarctic explorations their nitty-gritty has been crucial to combatting scurvy and their eggs a life - sustaining intellectual nourishment source . If you think eating penguin testis is weird , just waitress until you hear about the enquiry team who dined on50,000 - yr - old bison .
Gentoo ballock are an often mentioned form in old south-polar recipe books , possibly because they have a longer pose time of year and will lay more than one , unlike Emperor penguins whose reproductive winner rest on a single ballock per season . Gentoos can also relay if they suffer eggs to marauder , though this can hold up their fosterage time of year the next year .

“ I chiefly fuck Gentoo eggs , the most usual ones , and can draw these , ” said Headland , who has been exploring both icy realm since 1977 . “ It is not well-off to get them fresh unless laying is seen in progress . Addled ones sometimes explode with the pressing of decomposed contents . ”
Delicious . As for their appearance , they are not needfully unlike those of the waterfowl eggs most people are more familiar with . But something reasonably unearthly hap when they boil .
What does a penguin egg that’s been boiled look like?
“ They are about duck’s egg egg size , large and more rounded than those of hens . The shell is deep and stronger than that of a biddy and some precaution is postulate on cracking one without work a lot . The uncooked albumen is translucent with a svelte greenish tone liken to that of a hen . The vitellus is much bright , much more orangish [ than ] a hen ’s , ” Headland differentiate IFLScience .
“ On cooking , boiling ( about 10 arcminute ) , or frying , the albumin coagulates but remains translucent , it does not white . [ The ] yolk solidifies and retains its undimmed colour . If the eggs are whipped , for an omelet , or scrambled , the answer is not greatly unlike from hen , duck , or most other eggs . ”
As for why the eggs do this fussy magic caper , grant to thePolar Guidebook , it ’s to do with the proportion of glycoprotein they contain . While poulet nut are rich in mostly albumen , penguin eggs hold back 25 percentpenalbumin , which helps them to survive in the region ’s freezing temperatures .

How else have penguin eggs been eaten historically?
So , the Tweets were dead on target . If you boil a penguin nut it does go see - through . If you ’ve also heard that penguin eggs make for bully meringue – something we stumbled across while researching moil penguin nut – this too seems to be true , as Donald Morrison who lives in the Falklands Islands found out firsthand .
In the Falkland Islands , the local anaesthetic , know as “ Kelpers ” , are outmatched by the resident penguins , with a human universe of around 3,500 and more than a million penguins . nutrient for humans is a complex issue , as while the Kelpers have access to more meat and fish than they could consume , unused garden truck is much concentrated to come by .
Their thin and acidic soil is badly - suited to husbandry , meaning they have to import most of their fresh produce at a considerable monetary value . According to a characteristic from theBBC , half a white lettuce costs $ 7.53 ( £ 6.18 ) while three - to - four zucchinis could be as much as $ 8.81 ( £ 7.23 ) .

Apparently vinegar, and being very, very hungry, can improve the flavor. Image courtesy ofDonald Morrison
This has meant that Kelpers have memorize to get the most out of what is available to them , which historically has include pickling and preserving the eggs of geese , hens , and – yep – penguins . According to Morrison , Gentoo penguin bollock can still be consumed and eaten but only by license holders , of which his friend was one . It ’s illegal to pull together the testicle otherwise .
Elsewhere , pull together penguin eggs is mostly illegal in areas where humans and penguins traverse over . Antarctica does not and has never had an autochthonic universe , but there was a time when Internet Explorer rely on “ egging ” to keep their intellectual nourishment stock up during expeditions .
“ Penguin orchis collection was done by several ' grand age ' expeditions at the time when the boo arrived in their genteelness rookeries in the leaping , ” said Headland . “ Shells of some of these , now dry and empty , may still be seen in a few of the historical hut . It was essential to be early and quick to attempt to get a tumid supply which , with guardianship , could last till winter . ”

What does a penguin egg taste like?
As for how a roil penguin testicle smack , it seems that even without the illegality of their consumption , you probably would n’t find many people chomping at the bit to chew on their translucent , oily albumen .
“ The taste is passably fishy as krill mold a major part of the dieting , ” said Headland . “ A personal comment is that penguin eggs taste much better when you are hungry . ”
“ They were n’t so tasty once boiled and needed vinegar to make them edible , ” suppose Morrison , but “ I made a pavlova with one egg , and it was beautiful . ”
So , in conclusion : Penguin eggs boil clear , taste like Pisces , and make great pavlovas .
There , that ’s something you know now .
