A poached egg is firm on the outside and has a runny golden yolk in the center. It’s perfect with buttered toast, avocado toast, eggs benedict, or pasta. Although delicious, it can be hard to make. Some mistakes people make when poaching eggs include using water that is too cold or too hot, swirling the water too much, adding too many eggs to the pot, and using old eggs. Make sure to use fresh eggs when making poached eggs so the whites hold together better.
