   The Scientist's Formula:

9. 9

   Four researchers at the Department of Food Science at Leeds University in the UK spent more than 1,000 hours testing 700 variations on the traditional bacon sandwich.

10. 10

    They tried different types and cuts of bacon, cooking techniques, types of oil and a range of cooking times at different temperatures.

11. 11

    A shortlist was then tested with computers to measure the texture of each sandwich.

12. 12

    Fifty volunteers also judged each sandwich according to its taste, texture and flavour.

13. 13

    The formula is: N = C + {fb (cm) . fb (tc)} + fb (Ts) + fc . ta, where N=force in Newtons required to break the cooked bacon, fb=function of the bacon type, fc=function of the condiment/filling effect, Ts=serving temperature, tc=cooking time, ta=time or duration of application of condiment/filling, cm=cooking method, C=Newtons required to break uncooked bacon.
