- The reason for skimming the scum off the surface off the liquid is to help prevent the stock going cloudy. It is easier to do this before the vegetables go in, otherwise they get in the way.

- When simmering the stock, make sure the heat is very low, there should be hardly any bubbles breaking the surface. Boiling the stock will result in it becoming bitter and cloudy.

- The best fish bones to use for stock are from flat fish such as turbot, halibot and sole. This is because they have a large surface area that contains a good amount of natural gelatine which sets the stock.
