What is the best way to poach an egg in a pan

Put a little white vinegar on a pot of boiling water and it makes the egg stay together

Just had one myself - this is what I do - get some salted water boiling, then turn it down to a simmer. Crack the egg into a dish and when the water is ready just slide the egg in there. You can get the water gently swirling if you like, to help the whites stay closer in. Simmer for about 3 minutes, then use a slotted spoon or scoop to fish it out, gently shake off the water, and then plop it onto just about anything for added goodness!
