what's the difference between all solar cooker.
Food temperatures
I've just changed the sentence that said no food can go above 100 C as it's not strictly true. Pure water boils at 100 C but as soom as you put something in it it boils at a very slightly higher temperature, for example jam can boil at 104 C . There is some food that can get much hotter if it contains sufficiently little water. Toffee for the extreme example needs a temperature of 150 C / 300 F. Obviously at altitude these boiling temperatures drop. 84.51.146.100 09:12, 15 April 2007 (UTC)
