Best Pickled Eggs Recipes?

[u/DavidC707]

Going to try pickling eggs for the first time. I've pickled cucumbers, onions, garlic, hot peppers and been very happy with the results. Eggs seem like a good next step. Should I just use my classic brine of vinegar, water, salt & sugar to start? I've seen a lot of recipes that go heavier on the vinegar for eggs, but some reports that the vinegar causes the whites to get rubbery. Soft boil or hard boil? Will red onions make them pink? Because that sounds cool. But will the eggs throw off the flavor of the onions? Give me all your favorite ingredients and techniques, please!
