That's because store bought eggs are not fresh.

Not fresh is an understatement in many parts of the world. In the U.K., it’s up to 60 days - and in the U.S., it’s common for eggs in grocery stores to have been laid 6 months previously.

I always think how come eggs can stay so fresh so long? Is there any other "whole" protein that stays fresh so long?

Wow, 6 months ?! Why? Supply is pretty continuous, can keep them pretty much anywhere (even if there was just one county in one state suitable for rearing hens.. you could post them to any other faster than that?), what introduces such delay?

Price stability requires a stockpile - there are egg warehouses dotted around the US, and they exist pretty much solely to ensure a regular supply and therefore predictable price of a very fundamental foodstuff.

Just another example of how Organic (clean food) propaganda isn't based in science. I can't tell you how often I hear cooks swear by their redish, darkwe yolk eggs for having some kind of magic properties. Interesting article, good read.

To complicate matters, psychology can play a significant role in the material result when making things. It's like the placebo effect but for the engineer, the cook, the mechanic, the designer etc.

Obviously cooking is about more than the ingredients, they are important, but timing and intuition play a big role, the latter can be undermined if they start without believing in the ingredients... this applies to programming just as much as cooking.

By law in the US farmers have up to 30 days to package eggs and then the eggs have to be sold within another 30 days, so the oldest eggs on the grocery shelf can be is 60 days. Most eggs are packaged and in a store for sale shortly after being laid.

Not too long ago in China, consumers preferred duck eggs with red tinted yolks. Market vendors would crack off the top half of an egg and display its yolk, and consumers thought the redder the better. So, of course, farmers started feeding a carcinogenic dye called Sudan Red directly to the ducks. * http://www.china.org.cn/english/health/189567.htm

Turmeric has had similar issues, with some individuals adding industrial lead chromate to improve the colors (and add to the weight, as it is sold by weight) https://www.washingtonpost.com/business/2019/09/28/turmeric-...

I'm a sucker for premium orange yolk eggs. My partner is sucker for buying eggs from a guy who grows them in his backyard. Sometimes, especially when making creamy scrambled eggs I can almost taste fishy or shellfish flavour (not something I like). We are based in NZ and I've heard people use sea shells as a source of calcium for hens, but I find hard to believe that it could be it.

The "fishy" taste is likely indicative of a higher omega 3 content, you get the same taste from 100% grass fed and finished beef and buffalo due to the higher omega 3 content.

This will happen if you feed your chickens salmon or other fish. I have chickens and yes I occasionally my sons or wife will feed them left overs and it may be some salmon skin we did not eat, some fish bones and heads that we did not eat, etc. When we do this the eggs take on that taste. I don't like it either and if it does happen then I feed those eggs to the dog....

EU legislation is that best before dates are at most 28 days from date of lay. Has the UK changed its law after Brexit? Not to my knowledge.

Red Lion stamped eggs still advertise the 28 day best before date. “For Lion eggs this must be shown on the shell (although this is not a legal requirement). Eggs have to be collected from farms at least twice a week and in practice most Lion eggs are delivered to the supermarket within 48 hours of being laid.”

Chinese markets strike me as absolutely brutal.

I mean, there is always some theft, fraud etc. in any market (one of the oldest written records of humanity is a customer complaint about bad copper sold by a certain Mesopotamian merchant called Ea-nasir in 1750 BC), but stuff like poisoning your customers with Sudan Red, or adding melamine to yoghurt, or frying food on gutter oil seems to always be reported from China.
