Its the weakest link that you need to address first.
The 'weakest link' in our dietary protein is the couple methionine - cysteine, as they are most scarce. If you manage to make them equally scarce as the cphenylalanine - tyrosine couple, you already have come a long way.
How to do that?
By consuming high quality protein (which is high in methionine - cystein); check out the Protein Quality of Different Proteinacous Foods list on this page:
http://www.waiworld.com/waidiet/nut-fruitprotein.html
And would eating these foods theoretically counteract the negatives of eating low-quality protein?
Yes; a relative lack of methionine / cysteine is counteracted by consuming food high in methionine / cysteine.

But the list of 'high quality protein' items is suppose to represent foods with as equal a ratio of amino-acids as possible. I was wondering if there's anything that has more methionine / cysteine and less of other amino-acids, so that in itself it would be lower quality, but when mixed with something deficient in these it would balance out.

But maybe there are no foods that have more methionine / cysteine than other amino acids.

No, it represents foods with the highest ratio of methionine + cysteine versus total protein.
Thats because we showed you on that page that you will always consume more of all the other amino acids (relative to requirements)

Thats exactly what the list is about;
Most methionine + cysteine relative to total protein (total of all amino acids combined)
, so that in itself it would be lower quality
No, because even if you consume such (high methionine + cysteine relative tot total protein) foods,
methionine and cysteine are still the least represented amino acids (relative to requirements).
maybe there are no foods that have more methionine / cysteine than other amino acids.
Exactly.
But if they would, they would be on top of the list,
because they would bring your amino acid ratio more into balance.
Why isnt our diet more balanced regarding amino acids?
Because redundant amino acids are fuel, and the nitrogen
(if not too much protein is consumed) is re-used for building non-essential amino acids.

Thanks, that makes sense.

Just as a side note, I'm pretty certain you can only get linolenic-acid omega 3 from a plant source, and none of the other (more important) omega 3s which only can come from animals.

This makes me wonder, the egg-yolks which are given flax-seeds and are therefor suppose to be high omega 3, must also contain only (or mostly) linolenic acid; which would make fatty fish more important.

Well, our body (and that of hens) is to some extend able to convert
alpha-linolenic acid into other omega 3 fats.
It very much differs 'to what extend'.
