In a bowl, add self raising flour, salt and caster sugar.  Mix well.
Add the egg and whole milk.  Whisk thoroughly until a medium thick, smooth batter is formed, adding a little more milk if necessary.  Set aside in the fridge for 30 minutes.
Heat a frying pan over a medium heat.  Add a touch of oil or butter to lightly grease the pan.  This will ensure the pancakes don't stick to the pan as they cook.
Pour 1 ladle of batter into the pan and cook the pancake for around 1 minute on the first side.  When bubbles are formed and the pancake begins to set around the edges, use a flat spatula to flip the pancake.  Cook for a further 30-40 seconds on the other side.  Repeat the process with the remaining batter, stacking the pancakes in a clean, dry tea towel as they are cooked.
Serve the pancakes with your favourite toppings (in this case, crispy bacon, maple syrup and softened butter).
