Poached Eggs Mystery
Over the weekend I poached a dozen eggs at my parents' house - now, I've poached a lot of eggs in recent memory but never have they turned out like they did here. I followed my usual method, but each one ended up overcooked on the bottom even though the whites were almost raw on top. (I had to cook them almost twice as long as usual just to feel confident that the whites were cooked enough). Same with the yolk - half was the consistency of hard boiled egg, the other half nice and runny. The shape was also different, a bit flatter instead of a nice ball.
The only factors that I can come up with that were different are: induction cooktop, hard water (softened with salts), and the eggs are from a different area (Midwest versus Pacific NW, but still free range). They were possibly a bit on the old side of ideal but I've poached old eggs before and have never had this issue.
Wondering if it was the induction that caused it? If so, suggestions for how to compensate?
