Using eye-dropper, deposit a single drop of vinegar on top of each egg sitting in carton. Keep carton in fridge while leaving carton lid slightly open.

After some hours, take syringe and suck up some suitable marinade (eg. soya sauce, or chili-infused soya sauce, etc). Use syringe to pierce eggshell where droplet was, and inject the marinade (don't insert syringe too deep)

I don't feel it's necessary, but perhaps a dab of some some foodstuff could be used to seal the hole to avoid air-induced accelerated spoilage of egg interior. ChatGPT suggested an improvised paste from flour+water, or else beeswax. Anybody else have alternative suggestions?

Reason why I don't feel it's that necessary, is because the marinade would be sitting above the egg yolk in the upper pointy part of the egg, forming its own liquid barrier against the outside air.

Actually, I just read that the air cavity inside an egg forms on the big end of the egg. In which case, in order for our marinade to sit in that gap, you'd have to have the egg sitting with the pointy end down and fat end up, to then do the injection on the fat end.

Hmm, this might necessitate the construction of a modified egg carton.

Not new to you maybe.
Dang, that's pretty inventive.
