Melt the butter (or whatever) and let it cool down. Clearly if you are using oil you don't need to melt it.
Beat the eggs with the milk (or milk substitute)
Sieve the flour of your choice and the baking powder into a big bowl. Add the sugar and the salt and give it a stir.
Uncover the bowl of refreshed starter and stir in the egg and milk (or whatever) mixture and the melted butter (or whatever).
Add this to the dry ingredients and whisk well to get rid of any lumps.
Let the batter sit for 30 minutes or so. Have a shower! Have a cup of coffee and read the paper! If you are desperate, don't bother letting it sit (but make sure there are no lumps).
Heat the frying pan to medium-high and add a little blob of butter or splash of oil. Let it sizzle up and then wipe it out with a cloth.
Give the batter a little, last whisk and then use a jug or a ladle to pour the batter in the pan to make pancakes the size you like them.
If using, scatter the fruit of your choice on top of the pancakes and wait until bubbles for on the top and the edges begin to brown. Then flip them over and continue to cook them for a good 2-3 minutes to cook the other side and the centre.
Keep the pancakes warm in the oven, as you cook all of them.
Serve with the toppings of your choice
