Step aside E=MC squared, because scientists at the Royal Society of Chemistry have figured out the formula (see above) for the perfect grilled cheese sandwich.
...the perfect slice can be made by melting 50 grams of sliced hard cheese, such as cheddar, on a slice of white bread, 10mm thick, under the grill. The cheese on toast should sit at a distance of 18cm from the heat source – which in our grill was at a temperature of 115oC – and needs to cook for four minutes to achieve the perfect consistency and taste.
No word yet on what George Foreman's thoughts are on this.
