Everyone has "the best" approach to poaching an egg, just like every region has the best barbecue sauce and every Jewish mother has the best matzoh ball soup recipe. There's a lot of conflicting information out there. Is a splash of vinegar necessary? Should you crack the eggs in a separate cup first?
The Kitchn seems to have found the truth to perfectly runny yolks and firm whites. The method comes from Delia Smith's Complete How to Cook. The UK food personality recommends pouring hot water from a kettle into a large, shallow pan and heating it until little bubbles start to form. Then break the eggs one by one into the water and let them barely simmer for exactly one minute. Remove the pan from the heat and allow the eggs to sit in the hot water for another ten minutes. Do you agree?
