Here we go again, run up to Christmas and the food pages are full of useful hints and tips on how to roast the perfect turkey, giving people a timing of mins per 450 g/lb. Not very useful when pack weights are in kg only! [article contributed by Roz Denny]
Working on this illogical logic, the ‘useful’ hint should start:
- Get out your calculator.
- Work out how many 450 g there are in your pre-weighed (in kg) bird dividing by 0.450.
- Multiply by the 450 g units by time in mins.
Compare this to a useful timing of mins per kg:
- Multiply the time in mins by the kg weight.
(However, if you are following an old recipe from a favourite cookbook for other birds e.g goose or duck or a joint of beef/ham/pork, simply multiply the mins pr 450 g/ lb by 2.2 to get the kg weight timings).
