Poached egg

I saw on TV Nigella Lawson poaching an egg. She used a method I haven't seen before. She put the egg into a small sieve so that the watery part of the white drained out. (This is the part that usually makes a frothy mess during the poaching process.) She then put the rest of the egg into a cup and added about a teaspoon of lemon juice to tighten up the white. Finally she slid the egg into the pan of water, with the water barely moving. Her egg turned out a perfect oval.
