In order to poach two eggs at a time and make sure they stay together when poaching them, you need to make sure they both go into the swirling water at the same time. So begin by breaking two eggs into a ramekin or similar sized dish.
Then, bring a pan full of water to the boil in a saucepan and stir in a cap-full of vinegar and a pinch of salt. The vinegar will help keep the eggs together.
Turn the heat down to your hobs lowest setting until the bubbles in the pan stop. Now make a swirling whirlpool in the water using a dessert or table spoon. Whilst the water is still spinning, quickly (but carefully) pour the eggs into the centre of the whirlpool and poach as normal.
You may find it'll take a minute or two longer to poach as you're cooking two eggs, leave for 5-6 minutes for a runny centre, or a bit longer for a hard centre. And that's the secret to poaching more than one egg at a time.
