Scientists create ‘perfect’ toast

Equation for Perfect Toast

<a href="http://news.bbc.co.uk/2/hi/uk_news/3248822.stm">BBC NEWS | UK | Scientists create &lsquo;perfect&rsquo; toast</a>: &ldquo;Researchers&rsquo; found that people think the perfect piece of toast should have partly melted butter patches on it, improving its taste and texture.



&ldquo;For this to work, the butter should be applied at fridge temperature of five degrees Celsius, the equation shows&hellip;



&ldquo;The equation relates to the critical amount of butter, applied at fridge temperature (approximately five degrees Celsius or 41&deg;F), required to produce this effect.



&ldquo;H represents thickness, Cp the specific heat, P density, T the initial temperature of the toast, w the weight, and subscript a and b toast and butter respectively&hellip;



&ldquo;&lsquo;To produce the patches of butter most people said they preferred, the bread needs to be heated to at least 120&deg;C, and the butter should be used straight from the fridge, applied unevenly within two minutes of the bread coming out of the toaster.



&ldquo;&lsquo;The amount of butter should be about one-seventeenth the thickness of the bread,&rsquo; he said.&rdquo;
