Most of us are happy to slap two pieces of bread together with a few slices of cheddar and, if we're lucky, a squirt of salad cream to make a good cheese sarnie.
But it seems the process may have just become a bit more complicated than that.
Not content with their usual figures and algebra, scientists have discovered a mathematical formula for creating the perfect cheese sandwich.
The formula:
W [1 + ((bd)/6.5)) - s + ((m-2c)/2) + ((v+p)/7t)] (100 + l/100) W = the thickness of Cheddar in millimetres B = The thickness of the bread D = The dough flavour modifier S = The thickness of margarine or butter M = The thickness of mayonnaise C = The creaminess modifier V = The thickness of tomato P = The depth of pickle T = The tanginess modifier I = The thickness of the lettuce layer Scientists discover a new mathematical formula...for the perfect cheese sandwich | Mail Online
