OVEN TEMPERATURES

  • Found a recipe you want to try but, unfortunately, it only gives oven temperatures in degrees Fahrenheit and you cook by gas - what is the gas mark equivalent?
  • What is meant by "cook in a moderate oven"?
  • My new cooker has Celsius markings, how do I convert my old recipes?

These are all queries I have received over the past few months, so I thought this page may prove useful to others -

 Fan assisted ovens are usually set approximately 25 degrees Celsius (i.e. approximately 50 degrees Fahrenheit) lower than others and cooking time is reduced by 10 minutes for every hour of cooking time.

Different manufacturers and oven types do vary, so always refer to your cooker instruction book.
